【期刊论文】Heat Kernels and the Index Theorems on Even and Odd Dimensional Manifolds*
张伟平, Weiping Zhang†
ICM 2002·Vol. Ⅲ·1-3,-0001,():
-1年11月30日
In this talk, we review the heat kernel approach to the Atiyah-Singer index theorem for Dirac operators on closed manifolds, as well as the Atiyah-Patodi-Singer index theorem for Dirac operators on manifolds with boundary. We also discuss the odd dimensional counterparts of the above results. In particular, we describe a joint result with Xianzhe Dai on an index theorem for Toeplitz operators on odd dimensional manifolds with boundary.

【期刊论文】SYMPLECTIC REDUCTION AND A WEIGHTED MULTIPLICITY FORMULA FOR TWISTED SPINC-DIRAC OPERATORS∗
张伟平, YOULIANG TIAN† AND WEIPING ZHANG‡
ASIAN J. MATH. Vol. 2, No.3, pp. 591-608, September 1998,-0001,():
-1年11月30日
We extend our earlier work in [TZ1], where an analytic approach to the Guillemin-Sternberg conjecture [GS] was developed, to cases where the Spinc-complex under consideration is allowed to be further twisted by certain exterior power bundles of the cotangent bundle. The main result is a weighted quantization formula in the presence of commuting Hamiltonian actions. The corresponding Morse-type inequalities in holomorphic situations are also established.

【期刊论文】An analytic proof of the geometric quantization conjecture of Guillemin-Sternberg
张伟平, Youliang Tian, *, Weiping Zhang, **
Invent. math. 132, 229-259(1998),-0001,():
-1年11月30日
We present a direct analytic approach to the Guillemin-Sternberg conjecture [GS] that geometric quantization commutes with symplectic reduction', which was proved recently by Meinrenken [M1], [M2] and Vergne [V1], [V2] et al. Besides providing a new proof of this conjecture, our methods also lead immediately to further extensions in various contexts.
