Dirac operators coupled to vector potentials
AUTOR(ES)
Atiyah, M. F.
RESUMO
Characteristic classes for the index of the Dirac family [unk]A are computed in terms of differential forms on the orbit space of vector potentials under gauge transformations. They represent obstructions to the existence of a covariant Dirac propagator. The first obstruction is related to a chiral anomaly.
