Spinorially twisted Spin structures, I: curvature identities and eigenvalue estimates
arXiv:1409.6246 · doi:10.1016/j.difgeo.2016.01.008
Abstract
We define (higher rank) spinorially twisted spin structures and deduce various curvature identites as well as estimates for the eigenvalues of the corresponding twisted Dirac operators.
We have corrected typos and simplified/shortened the preliminaries section
