Inverse Linear Problems on Hilbert Space and their Krylov Solvability
Original price was: ₹ 9,509.00.₹ 7,607.00Current price is: ₹ 7,607.00.
This book presents a thorough discussion of the theory of abstract inverse linear problems on Hilbert space. Given an unknown vector f in a Hilbert space H, a linear operator A acting on H, and a vector g in H satisfying Af=g, one is interested in approximating f by finite linear combinations of g, Ag, A2g, A3g, … The closed subspace generated by the latter vectors is called the Krylov subspace of H generated by g and A. The possibility of solving this inverse problem by means of projection methods on the Krylov subspace is the main focus of this text.After giving a broad introduction to the subject, examples and counterexamples of Krylov-solvable and non-solvable inverse problems are provided, together with results on uniqueness of solutions, classes of operators inducing Krylov-solvable inverse problems, and the behaviour of Krylov subspaces under small perturbations. An appendix collects material on weaker convergence phenomena in general projection methods.
This subject of this book lies at the boundary of functional analysis/operator theory and numerical analysis/approximation theory and will be of interest to graduate students and researchers in any of these fields.

This volume provides an introduction to the theory of Mean Field Games, suggested by J.-M. Lasry and P.-L. Lions in 2006 as a mean-field model for Nash equilibria in the strategic interaction of a large number of agents. Besides giving an accessible presentation of the main features of mean-field game theory, the volume offers an overview of recent developments which explore several important directions: from partial differential equations to stochastic analysis, from the calculus of variations to modeling and aspects related to numerical methods. Arising from the CIME Summer School 'Mean Field Games' held in Cetraro in 2019, this book collects together lecture notes prepared by Y. Achdou (with M. Laurière), P. Cardaliaguet, F. Delarue, A. Porretta and F. Santambrogio.These notes will be valuable for researchers and advanced graduate students who wish to approach this theory and explore its connections with several different fields in mathematics.

Méthodes mathématiques en chimie quantique. Une introduction
Original price was: ₹ 7,132.00.₹ 5,705.00Current price is: ₹ 5,705.00.
Ce cours est une introduction à la modélisation mathématique et à l'analyse numérique pour la chimie moléculaire quantique, un champ peu connu des mathématiciens et pourtant riche en sujets d'investigation. Le point de vue choisi est celui du mathématicien appliqué. Le cours est construit de manière auto-consistante. Seules des notions de base en analyse fonctionnelle sont requises pour l'aborder. Les outils mathématiques plus élaborés sont introduits progressivement et les connaissances nécessaires en physique et en théorie spectrale sont regroupées dans des annexes. On présente d'abord les modèles les plus utilisés en pratique. Puis, on analyse ces modèles d'un point de vue mathématique (questions d'existence de solutions, d'unicité, ...). On introduit ensuite les différentes stratégies numériques employées pour la résolution pratique, et on fournit, quand ceci est possible, des éléments d'analyse numérique de ces méthodes. Les liens existants entre les modèles de la chimie moléculaire et des sujets connexes sont aussi explorés : modélisation de la phase liquide, physique de l'état cristallin, biologie, simulation des matériaux, ... Le cours peut aussi intéresser le chimiste ou le physicien curieux de comprendre les techniques mathématiques dont relèvent les modèles qu'il utilise, et de découvrir comment de telles techniques peuvent améliorer significativement l'efficacité et la qualité des simulations numériques.

Navier–Stokes Equations
Original price was: ₹ 11,411.00.₹ 9,129.00Current price is: ₹ 9,129.00.
This volume is devoted to the study of the Navier–Stokes equations, providing a comprehensive reference for a range of applications: from advanced undergraduate students to engineers and professional mathematicians involved in research on fluid mechanics, dynamical systems, and mathematical modeling. Equipped with only a basic knowledge of calculus, functional analysis, and partial differential equations, the reader is introduced to the concept and applications of the Navier–Stokes equations through a series of fully self-contained chapters. Including lively illustrations that complement and elucidate the text, and a collection of exercises at the end of each chapter, this book is an indispensable, accessible, classroom-tested tool for teaching and understanding the Navier–Stokes equations.
Incompressible Navier–Stokes equations describe the dynamic motion (flow) of incompressible fluid, the unknowns being the velocity and pressure as functions of location (space) and time variables. A solution to these equations predicts the behavior of the fluid, assuming knowledge of its initial and boundary states. These equations are one of the most important models of mathematical physics: although they have been a subject of vivid research for more than 150 years, there are still many open problems due to the nature of nonlinearity present in the equations. The nonlinear convective term present in the equations leads to phenomena such as eddy flows and turbulence. In particular, the question of solution regularity for three-dimensional problem was appointed by Clay Institute as one of the Millennium Problems, the key problems in modern mathematics. The problem remains challenging and fascinating for mathematicians, and the applications of the Navier–Stokes equations range from aerodynamics (drag and lift forces), to the design of watercraft and hydroelectric power plants, to medical applications such as modeling the flow of blood in the circulatory system.
