Résumé
This book is intended for students who wish to get an
introduction to the theory of partial differential
equations. The author focuses on elliptic equations and
systematically develops the relevant existence schemes,
always with a view towards nonlinear problems. These are
maximum principle methods (particularly important for
numerical analysis schemes), parabolic equations,
variational methods, and continuity methods. This book also
develops the main methods for obtaining estimates for
solutions of elliptic equations: Sobolev space theory, weak
and strong solutions, Schauder estimates, and Moser
iteration. Connections between elliptic, parabolic, and
hyperbolic equations are explored, as well as the
connection with Brownian motion and semigroups. This book
can be utilized for a one-year course on partial
differential equations.
Jürgen Jost is Director of the Max Planck Institute for
Mathematics in the Sciences and Professor of Mathematics at
the University of Leipzig. He is the author of a number of
Springer books, including Postmodern Analysis (1998),
Compact Riemann Surfaces (1997) and Riemannian Geometry and
Geometric Analysis (1995). The present book is an expanded
translation of the original German version, Partielle
Differentialgleichungen (1998).
