Lectures On Chern-weil Theory And Witten Deformations

Based on the notes of a graduate course on differential geometry, this volume contains an introduction to the geometric theory of characteristic classes due to Shiing-shen Chern and Andr Weil, as well as presenting the Morse inequalities based on deformations introduced by Edward Witten.

This invaluable book is based on the notes of a graduate course on differential geometry which the author gave at the Nankai Institute of Mathematics. It consists of two parts: the first part contains an introduction to the geometric theory of characteristic classes due to Shiing-shen Chern and André Weil, as well as a proof of the Gauss-Bonnet-Chern theorem based on the Mathai-Quillen construction of Thom forms; the second part presents analytic proofs of the Poincaré-Hopf index formula, as well as the Morse inequalities based on deformations introduced by Edward Witten.
