In the first edition of this book, simple proofs of the Atiyah-Singer Index Theorem for Dirac operators on compact Riemannian manifolds and its generalizations (due to the authors and J.-M. Bismut) were presented, using an explicit geometric construction of the heat kernel of a generalized Dirac operator; the new edition makes this popular book available to students and researchers in an attractive paperback.
Heat Kernels and Dirac Operators
Using the heat kernels theory of Berline, Getzler and Vergne, Duistermaat revisits some fundamental concepts of the theory, and presents the application to symplectic geometry.
This book is an outgrowth of the notes in which I worked this out. For me this was a great learning experience because of the many beautiful mathematical structures which are involved.

Elliptic Operators, Topology, and Asymptotic Methods
This book treats the Atiyah-Singer index theorem using the heat equation, which gives a local formula for the index of any elliptic complex.
Based on the lecture notes of a graduate course given at MIT, this sophisticated treatment leads to a variety of current research topics and will undoubtedly serve as a guide to further studies.
From reviews of the 2nd Edition: "..the new edition of Professor Wells' book is timely and welcome...an excellent introduction for any mathematician who suspects that complex manifold techniques may be relevant to his work.
