Title: (1,1)-forms Acting On Spinors On Kahler Surfaces
Author: Leao
Rafael de Freitas
Abstract: It is known that, for Dirac operators on Riemann surfaces twisted by line bundles with Hermitian-Einstein connections, it is possible to obtain estimates for the first eigenvalue in terms of the topology of the twisting bundle [8]. Attempts to generalize topological estimates for higher rank bundles or higher dimensional manifolds have been so far unsuccessful. In this work, we construct a class of examples, making explicit one problem that must be addressed in attempts to generalize such topological estimates.
