Eta-invariants, Torsion forms and Flat vector bundles

Xiaonan Ma, weiping Zhang

We present a new proof, as well as a extension, of the Riemann-Roch-Grothendieck theorem of Bismut-Lott for flat vector bundles. The main techniques used are the comput…

Eta invariant and Chern-Simons current

Weiping Zhang

We show that the R/Z part of the analytically defined eta invariant of Atiyah-Patodi-Singer for a Dirac operator on an odd dimensional closed spin manifold can be expressed purely…

Circle actions and Z/k-manifolds

Weiping Zhang

We establish an S^1-equivariant index theorem for Dirac operators on Z/k-manifolds. As an application, we generalize the Atiyah-Hirzebruch vanishing theorem for S^1-actions on clos…

Modular invariance, characteristic numbers and invariants

Fei Han, Weiping Zhang

We generalize the "miraculous cancellation" formulas of Alvarez-Gaumé, Witten and Kefeng Liu to a twisted version where an extra complex line bundle is involved. We also apply our…

An Index Theorem for Toeplitz Operators on Odd Dimensional Manifolds with Boundary

Xianzhe Dai, Weiping Zhang

We establish an index theorem for Toeplitz operators on odd dimensional spin manifolds with boundary. It may be thought of as an odd dimensional analogue of the Atiyah-Patodi-Singe…

Rigidity and Vanishing Theorems in K-Theory II

Kefeng Liu, Xiaonan Ma, Weiping Zhang

We extend our family rigidity and vanishing theorems in [{\bf LiuMaZ}] to the Spin^c case. In particular, we prove a K-theory version of the main results of [{\bf H}], [{\bf Liu1},…
