Book Synopsis Hilbert Functions of Filtered Modules by : Maria Evelina Rossi
Download or read book Hilbert Functions of Filtered Modules written by Maria Evelina Rossi and published by Springer Science & Business Media. This book was released on 2010-08-25 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hilbert Functions play major roles in Algebraic Geometry and Commutative Algebra, and are becoming increasingly important also in Computational Algebra. They capture many useful numerical characters associated to a projective variety or to a filtered module over a local ring. Starting from the pioneering work of D.G. Northcott and J. Sally, we aim to gather together in one place many new developments of this theory by using a unifying approach which gives self-contained and easier proofs. The extension of the theory to the case of general filtrations on a module, and its application to the study of certain graded algebras which are not associated to a filtration are two of the main features of the monograph. The material is intended for graduate students and researchers who are interested in Commutative Algebra, in particular in the theory of the Hilbert Functions and related topics.
Book Synopsis Growth Conditions on Hilbert Functions of Modules by : Roger D. Dellaca
Download or read book Growth Conditions on Hilbert Functions of Modules written by Roger D. Dellaca and published by . This book was released on 2015 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gotzmann's Regularity Theorem uses a binomial representation of the Hilbert polynomial of a standard graded algebra to establish a bound on Castelnuovo-Mumford regularity. Using this and his Persistence Theorem, Gotzmann provided an explicit construction of the Hilbert scheme. This author will show that Gotzmann's Regularity Theorem cannot be extended to arbitrary modules. However, under an additional assumption on the generating degrees of a module, Gotzmann's Regularity Theorem will be proven. The modules satisfying the additional assumption will correspond to globally generated coherent sheaves. This will be used to provide an explicit construction of the Quot scheme. The Gotzmann Regularity bound is known to be strict for standard graded algebras, but not for globally generated coherent sheaves. In order to address this, new representations for the Hilbert function and Hilbert polynomial are given that account for the rank and generating degrees of a module. Generalizations of the theorems of Macaulay, Green, and Gotzmann will be proven using these representations. The generalized Gotzmann number will give a strict upper bound for the regularity of modules generated in degree zero. Additionally, these representations will be used to prove a sharp inequality on the first and second Chern classes of a globally generated coherent sheaf.
Book Synopsis Differential and Difference Dimension Polynomials by : Alexander V. Mikhalev
Download or read book Differential and Difference Dimension Polynomials written by Alexander V. Mikhalev and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of Hilbert polynomials in commutative and homological algebra as well as in algebraic geometry and combinatorics is well known. A similar role in differential algebra is played by the differential dimension polynomials. The notion of differential dimension polynomial was introduced by E. Kolchin in 1964 [KoI64]' but the problems and ideas that had led to this notion (and that are reflected in this book) have essentially more long history. Actually, one can say that the differential dimension polynomial describes in exact terms the freedom degree of a dynamic system as well as the number of arbitrary constants in the general solution of a system of algebraic differential equations. The first attempts of such description were made at the end of 19th century by Jacobi [Ja890] who estimated the number of algebraically independent constants in the general solution of a system of linear ordinary differential equations. Later on, Jacobi's results were extended to some cases of nonlinear systems, but in general case the problem of such estimation (that is known as the problem of Jacobi's bound) remains open. There are some generalization of the problem of Jacobi's bound to the partial differential equations, but the results in this area are just appearing. At the beginning of the 20th century algebraic methods in the theory of differen tial equations were actively developed by F. Riquier [RiqlO] and M.

Book Synopsis Commutative Algebra and its Interactions to Algebraic Geometry by : Nguyen Tu CUONG
Download or read book Commutative Algebra and its Interactions to Algebraic Geometry written by Nguyen Tu CUONG and published by Springer. This book was released on 2018-08-02 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents four lectures on recent research in commutative algebra and its applications to algebraic geometry. Aimed at researchers and graduate students with an advanced background in algebra, these lectures were given during the Commutative Algebra program held at the Vietnam Institute of Advanced Study in Mathematics in the winter semester 2013 -2014. The first lecture is on Weyl algebras (certain rings of differential operators) and their D-modules, relating non-commutative and commutative algebra to algebraic geometry and analysis in a very appealing way. The second lecture concerns local systems, their homological origin, and applications to the classification of Artinian Gorenstein rings and the computation of their invariants. The third lecture is on the representation type of projective varieties and the classification of arithmetically Cohen -Macaulay bundles and Ulrich bundles. Related topics such as moduli spaces of sheaves, liaison theory, minimal resolutions, and Hilbert schemes of points are also covered. The last lecture addresses a classical problem: how many equations are needed to define an algebraic variety set-theoretically? It systematically covers (and improves) recent results for the case of toric varieties.

Book Synopsis Extended Abstracts GEOMVAP 2019 by : Maria Alberich-Carramiñana
Download or read book Extended Abstracts GEOMVAP 2019 written by Maria Alberich-Carramiñana and published by Springer Nature. This book was released on 2021-12-04 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises an overview of twelve months of intense activity of the research group Geometry, Topology, Algebra, and Applications (GEOMVAP) at the Universitat Politècnica de Catalunya (UPC). Namely, it contains extended abstracts of the group meeting in Cardona and of the international Workshop of Women in Geometry and Topology aligned with a series of workshops in the topic. As such, it includes a panoramic view of the main research interests of the group which focus on varieties and manifolds from the algebraic, topological and differential perspective with a view towards applications. The GEOMVAP group has a long tradition working on various interfaces of algebra, geometry and topology. In the last decade, the group has become active contributor in interdisciplinary science and it is now focused on both a theoretical point of view and the transversal applications to several disciplines including Robotics, Machine Learning, Phylogenetics, Physics and Celestial Mechanics. The increasing interdisciplinarity of modern research and the fact that the boundaries between different areas of mathematics are vanishing, with a constant transfer of problems and techniques between them, makes it difficult to progress without a multidisciplinary approach. GEOMVAP gathers together experts in Algebraic, Symplectic and Arithmetic Geometry to stimulate the interaction between them and to allow the study of each object from different points of view. The book aims at established researchers, as well as at PhD and postdoctoral students who want to learn more about the latest advances in pure and applied Geometry and Topology.

Book Synopsis Kodaira-Spencer Maps in Local Algebra by : Bernd Herzog
Download or read book Kodaira-Spencer Maps in Local Algebra written by Bernd Herzog and published by Springer. This book was released on 2006-11-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph contributes to Lech's inequality - a 30-year-old problem of commutative algebra, originating in the work of Serre and Nagata, that relates the Hilbert function of the total space of an algebraic or analytic deformation germ to the Hilbert function of the parameter space. A weakened version of Lech's inequality is proved using a construction that can be considered as a local analog of the Kodaira-Spencer map known from the deformation theory of compact complex manifolds. The methods are quite elementary, and will be of interest for researchers in deformation theory, local singularities and Hilbert functions.
