Download or read book Tropical Intersection Theory and Gravitational Descendants written by Johannes Rau and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2010-03 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this publication a tropical intersection theory is established with analogue notions and tools as its algebro-geometric counterpart. The developed theory, interesting as a subfield of convex geometry on its own, shows many relations to the intersection theory of toric varieties and other fields. In the second chapter, tropical intersection theory is used to define and study tropical gravitational descendants (i.e. Gromov-Witten invariants with incidence and "Psi-class" factors). It turns out that many concepts of the classical Gromov-Witten theory such as the WDVV equations can be carried over to the tropical world.

Book Synopsis Divisors and Sandpiles by : Scott Corry
Download or read book Divisors and Sandpiles written by Scott Corry and published by American Mathematical Soc.. This book was released on 2018-07-23 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Divisors and Sandpiles provides an introduction to the combinatorial theory of chip-firing on finite graphs. Part 1 motivates the study of the discrete Laplacian by introducing the dollar game. The resulting theory of divisors on graphs runs in close parallel to the geometric theory of divisors on Riemann surfaces, and Part 1 culminates in a full exposition of the graph-theoretic Riemann-Roch theorem due to M. Baker and S. Norine. The text leverages the reader's understanding of the discrete story to provide a brief overview of the classical theory of Riemann surfaces. Part 2 focuses on sandpiles, which are toy models of physical systems with dynamics controlled by the discrete Laplacian of the underlying graph. The text provides a careful introduction to the sandpile group and the abelian sandpile model, leading ultimately to L. Levine's threshold density theorem for the fixed-energy sandpile Markov chain. In a precise sense, the theory of sandpiles is dual to the theory of divisors, and there are many beautiful connections between the first two parts of the book. Part 3 addresses various topics connecting the theory of chip-firing to other areas of mathematics, including the matrix-tree theorem, harmonic morphisms, parking functions, M-matrices, matroids, the Tutte polynomial, and simplicial homology. The text is suitable for advanced undergraduates and beginning graduate students.

Book Synopsis Homological Mirror Symmetry and Tropical Geometry by : Ricardo Castano-Bernard
Download or read book Homological Mirror Symmetry and Tropical Geometry written by Ricardo Castano-Bernard and published by Springer. This book was released on 2014-10-07 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between Tropical Geometry and Mirror Symmetry goes back to the work of Kontsevich and Y. Soibelman (2000), who applied methods of non-archimedean geometry (in particular, tropical curves) to Homological Mirror Symmetry. In combination with the subsequent work of Mikhalkin on the “tropical” approach to Gromov-Witten theory and the work of Gross and Siebert, Tropical Geometry has now become a powerful tool. Homological Mirror Symmetry is the area of mathematics concentrated around several categorical equivalences connecting symplectic and holomorphic (or algebraic) geometry. The central ideas first appeared in the work of Maxim Kontsevich (1993). Roughly speaking, the subject can be approached in two ways: either one uses Lagrangian torus fibrations of Calabi-Yau manifolds (the so-called Strominger-Yau-Zaslow picture, further developed by Kontsevich and Soibelman) or one uses Lefschetz fibrations of symplectic manifolds (suggested by Kontsevich and further developed by Seidel). Tropical Geometry studies piecewise-linear objects which appear as “degenerations” of the corresponding algebro-geometric objects.
Book Synopsis The Poisonwood Bible by : Barbara Kingsolver
Download or read book The Poisonwood Bible written by Barbara Kingsolver and published by Harper Collins. This book was released on 2009-10-13 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York Times Bestseller • Finalist for the Pulitzer Prize • An Oprah's Book Club Selection “Powerful . . . [Kingsolver] has with infinitely steady hands worked the prickly threads of religion, politics, race, sin and redemption into a thing of terrible beauty.” —Los Angeles Times Book Review The Poisonwood Bible, now celebrating its 25th anniversary, established Barbara Kingsolver as one of the most thoughtful and daring of modern writers. Taking its place alongside the classic works of postcolonial literature, it is a suspenseful epic of one family's tragic undoing and remarkable reconstruction over the course of three decades in Africa. The story is told by the wife and four daughters of Nathan Price, a fierce, evangelical Baptist who takes his family and mission to the Belgian Congo in 1959. They carry with them everything they believe they will need from home, but soon find that all of it—from garden seeds to Scripture—is calamitously transformed on African soil. The novel is set against one of the most dramatic political chronicles of the twentieth century: the Congo's fight for independence from Belgium, the murder of its first elected prime minister, the CIA coup to install his replacement, and the insidious progress of a world economic order that robs the fledgling African nation of its autonomy. Against this backdrop, Orleanna Price reconstructs the story of her evangelist husband's part in the Western assault on Africa, a tale indelibly darkened by her own losses and unanswerable questions about her own culpability. Also narrating the story, by turns, are her four daughters—the teenaged Rachel; adolescent twins Leah and Adah; and Ruth May, a prescient five-year-old. These sharply observant girls, who arrive in the Congo with racial preconceptions forged in 1950s Georgia, will be marked in surprisingly different ways by their father's intractable mission, and by Africa itself. Ultimately each must strike her own separate path to salvation. Their passionately intertwined stories become a compelling exploration of moral risk and personal responsibility.
Book Synopsis The Things They Carried by : Tim O'Brien
Download or read book The Things They Carried written by Tim O'Brien and published by HarperCollins. This book was released on 2009-10-13 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classic work of American literature that has not stopped changing minds and lives since it burst onto the literary scene, The Things They Carried is a ground-breaking meditation on war, memory, imagination, and the redemptive power of storytelling. The Things They Carried depicts the men of Alpha Company: Jimmy Cross, Henry Dobbins, Rat Kiley, Mitchell Sanders, Norman Bowker, Kiowa, and the character Tim O’Brien, who has survived his tour in Vietnam to become a father and writer at the age of forty-three. Taught everywhere—from high school classrooms to graduate seminars in creative writing—it has become required reading for any American and continues to challenge readers in their perceptions of fact and fiction, war and peace, courage and fear and longing. The Things They Carried won France's prestigious Prix du Meilleur Livre Etranger and the Chicago Tribune Heartland Prize; it was also a finalist for the Pulitzer Prize and the National Book Critics Circle Award.
Book Synopsis On the Origin of Species Illustrated by : Charles Darwin
Download or read book On the Origin of Species Illustrated written by Charles Darwin and published by . This book was released on 2020-12-04 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
Book Synopsis Genesis and Development of a Scientific Fact by : Ludwik Fleck
Download or read book Genesis and Development of a Scientific Fact written by Ludwik Fleck and published by University of Chicago Press. This book was released on 2012-09-05 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in German in 1935, this monograph anticipated solutions to problems of scientific progress, the truth of scientific fact and the role of error in science now associated with the work of Thomas Kuhn and others. Arguing that every scientific concept and theory—including his own—is culturally conditioned, Fleck was appreciably ahead of his time. And as Kuhn observes in his foreword, "Though much has occurred since its publication, it remains a brilliant and largely unexploited resource." "To many scientists just as to many historians and philosophers of science facts are things that simply are the case: they are discovered through properly passive observation of natural reality. To such views Fleck replies that facts are invented, not discovered. Moreover, the appearance of scientific facts as discovered things is itself a social construction, a made thing. A work of transparent brilliance, one of the most significant contributions toward a thoroughly sociological account of scientific knowledge."—Steven Shapin, Science
Book Synopsis A Framework for K-12 Science Education by : National Research Council
Download or read book A Framework for K-12 Science Education written by National Research Council and published by National Academies Press. This book was released on 2012-02-28 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Book Synopsis On Their Own Terms by : Benjamin A. Elman
Download or read book On Their Own Terms written by Benjamin A. Elman and published by Harvard University Press. This book was released on 2009-07-01 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: In On Their Own Terms, Benjamin A. Elman offers a much-needed synthesis of early Chinese science during the Jesuit period (1600-1800) and the modern sciences as they evolved in China under Protestant influence (1840s-1900). By 1600 Europe was ahead of Asia in producing basic machines, such as clocks, levers, and pulleys, that would be necessary for the mechanization of agriculture and industry. In the seventeenth and eighteenth centuries, Elman shows, Europeans still sought from the Chinese their secrets of producing silk, fine textiles, and porcelain, as well as large-scale tea cultivation. Chinese literati borrowed in turn new algebraic notations of Hindu-Arabic origin, Tychonic cosmology, Euclidian geometry, and various computational advances. Since the middle of the nineteenth century, imperial reformers, early Republicans, Guomindang party cadres, and Chinese Communists have all prioritized science and technology. In this book, Elman gives a nuanced account of the ways in which native Chinese science evolved over four centuries, under the influence of both Jesuit and Protestant missionaries. In the end, he argues, the Chinese produced modern science on their own terms.

Book Synopsis Science, Evolution, and Creationism by : Institute of Medicine
Download or read book Science, Evolution, and Creationism written by Institute of Medicine and published by National Academies Press. This book was released on 2008-01-28 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did life evolve on Earth? The answer to this question can help us understand our past and prepare for our future. Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable. In the book Science, Evolution, and Creationism, a group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including "intelligent design." The book explores the many fascinating inquiries being pursued that put the science of evolution to work in preventing and treating human disease, developing new agricultural products, and fostering industrial innovations. The book also presents the scientific and legal reasons for not teaching creationist ideas in public school science classes. Mindful of school board battles and recent court decisions, Science, Evolution, and Creationism shows that science and religion should be viewed as different ways of understanding the world rather than as frameworks that are in conflict with each other and that the evidence for evolution can be fully compatible with religious faith. For educators, students, teachers, community leaders, legislators, policy makers, and parents who seek to understand the basis of evolutionary science, this publication will be an essential resource.
