This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous étudions des équations cinétiques de la forme f/t + v. *#xf = q(f, f), t0, x, r#n, v, r#n, qui décrivent l'évolution d'un gaz ou d'un plasma dans lequel les particules subissent des collisions modélisées par l'opérateur q, dit - de Boltzmann : q(f, f) dv#* d b(v v#*,) (f'f'#* ff#*), - ou de Landau : q(f, f) = /v#i dv#*a#i#j(v v#*) (f♯*f/v#j ff#*/v#*#, #j). Les trois premières parties de cette thèse concernent les équations homogènes (indépendantes de x) #tf = q(f, f). On insiste particulièrement sur deux points : les collisions rasantes et la dissipation d'entropie. Dans la première partie, on étudie le problème de Cauchy associé aux équations de Boltzmann et de Landau homogènes (pour des sections efficaces réalistes et éventuellement singulières), des propriétés de régularité des solutions, ainsi que l'asymptotique des collisions rasantes qui permet de passer d'une équation à l'autre. La deuxième partie est consacrée au cas particulier des molécules maxwelliennes. Sous cette hypothèse, on effectue une étude détaillée du problème de Cauchy et du retour vers l'équilibre, ainsi que des liens entre théorie cinétique et théorie de l'information. Dans la troisième partie, on utilise les résultats précédents pour obtenir des estimations explicites sur la vitesse de retour vers l'équilibre dans le cas général. Dans la quatrième partie, on obtient des résultats partiels sur le problème de Cauchy pour l'équation de Landau inhomogène, et quelques estimations nouvelles sur l'équation de Boltzmann inhomogène. Enfin, dans la cinquième partie, on établit diverses formes conservatives de l'opérateur de Boltzmann, avec application à l'asymptotique des collisions rasantes.

Download or read book Nonlinear PDE’s in Condensed Matter and Reactive Flows written by Henri Berestycki and published by Springer Science & Business Media. This book was released on 2002-11-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear partial differential equations abound in modern physics. The problems arising in these fields lead to fascinating questions and, at the same time, progress in understanding the mathematical structures is of great importance to the models. Nevertheless, activity in one of the approaches is not always sufficiently in touch with developments in the other field. The book presents the joint efforts of mathematicians and physicists involved in modelling reactive flows, in particular superconductivity and superfluidity. Certain contributions are fundamental to an understanding of such cutting-edge research topics as rotating Bose-Einstein condensates, Kolmogorov-Zakharov solutions for weak turbulence equations, and the propagation of fronts in heterogeneous media.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the renown of the Fields Medals, J.C. Fields has been until now a rather obscure figure, and recovering details about his professional activities and personal life was not at all a simple task. This work is a triumph of persistence with far-flung archival and documentary sources, and provides a rich non-mathematical portrait of the man in all aspects of his life and career. Highly readable and replete with period detail, the book sheds useful light on the mathematical and scientific world of Fields' time, and is sure to remain the definitive biographical study. --Tom Archibald, Simon Fraser University, Burnaby, BC, Canada Drawing on a wide array of archival sources, Riehm and Hoffman provide a vivid account of Fields' life and his part in the founding of the highest award in mathematics. Filled with intriguing detail--from a childhood on the shores of Lake Ontario, through the mathematics seminars of late 19th century Berlin, to the post-WW1 years of the fragmented international mathematical community--it is a richly textured story engagingly and sympathetically told. Read this book and you will understand why Fields never wanted the medal to bear his name and yet why, quite rightly, it does. --June Barrow-Green, Open University, Milton Keynes, United Kingdom One of the little-known effects of World War I was the collapse of international scientific cooperation. In mathematics, the discord continued after the war's end and after the Treaty of Versailles had been signed in 1919. Many distinguished scientists were involved in the war and its aftermath, and from their letters and papers, now almost a hundred years old, we learn of their anguished wartime views and their struggles afterwards either to prolong the schism in mathematics or to end it. J.C. Fields, the foremost Canadian mathematician of his time, was educated in Canada, the United States, and Germany, and championed an international spirit of cooperation to further the frontiers of mathematics. It was during the awkward post-war period that J.C. Fields established the Fields Medal, an international prize for outstanding research, which soon became the highest award in mathematics. J.C. Fields intended it to be an international medal, and a glance at the varying backgrounds of the fifty-two Fields medallists shows it to be so. Who was Fields? What carried him from Hamilton, Canada West, where he was born in 1863, into the middle of this turbulent era of international scientific politics? A modest mathematician, he was an unassuming man. This biography outlines Fields' life and times and the difficult circumstances in which he created the Fields Medal. It is the first such published study.

Book excerpt: Featuring updated versions of two research courses held at the Centre Émile Borel in Paris in 2001, this book describes the mathematical theory of convergence to equilibrium for the Boltzmann equation and its relation to various problems and fields. It also discusses four conjectures for the kinetic behavior of the hard sphere models and formulates four stochastic variations of this model, also reviewing known results for these.
