Synopses & Reviews
This book deals with equations that have played a central role in the interplay between partial differential equations and probability theory. Most of this material has been treated elsewhere, but it is rarely presented in a manner that makes it readily accessible to people whose background is probability theory. Many results are given new proofs designed for readers with limited expertise in analysis. The author covers the theory of linear, second order partial differential equations of parabolic and elliptic type. Many of the techniques have antecedents in probability theory, although the book also covers a few purely analytic techniques. In particular, a chapter is devoted to the DeGiorgi-Moser-Nash estimates and the concluding chapter gives an introduction to the theory of pseudodifferential operators and their application to hypoellipticity, including the famous theorem of Lars Hörmander.
Review
"The book will capture your attention with elegant proofs preseated in an almost perfectly self-contained manner, with abundant talk in a lecturer's tone by the author himself, but with a little bit of an aficionado's taste. The book, arranged by idiosyncratically, has such a strong impact that, at the next moment, you may find yourself carried away in looking for mathematical treasures scattered here and there in each chapter. The reviewer recommends the present book with confidence to anyone who in interested in PDE and probability theory. At least you should always keep this at your side if you are a probabilist at all."

Synopsis
Explains the theory of linear and second order PDEs of parabolic and elliptic type.
Synopsis
This book provides probabilists with sufficient background to begin applying PDEs to probability theory and probability theory to PDEs. It covers the theory of linear and second order PDEs of parabolic and elliptic type. While most of the techniques described have antecedents in probability theory, the book does cover a few purely analytic techniques.
About the Author
Daniel W. Stroock is the Simons Professor of Mathematics at the Massachusetts Institute of Technology. His introduction to the study of partial differential equations was at the Courant Institute of Mathematical Sciences in courses by L. Nirenberg, P. Lax, and F. John. He is a member of the National Academy of Sciences and was the recipient of the 1996 AMS Steele Prize for seminal research together with S. R. S. Varadhan. This is Professor Stroock's seventh book.
