Revisits fundamental concepts of the heat kernel Lefschetz fixed point formula for the spin-c Dirac operator, using the heat kernel theories of Berline, Getzler, and Vergne, and presents its application to symplectic geometry. Treats subjects including Clifford modules, the Hirzebruch-Riemann-Roch integrand, and the orbifold version, and offers an appendix on equivariant forms. Annotation copyright Book News, Inc.
