报告题目：Family APS index theorem and equivariant eta form

报告摘要：The general version of the family APS index theorem was established by Melrose andPiazza in 1997 by using the b-calculus and the spectral section. The boundary term there is the eta form with perturbation. In this talk, we will generalize the spectral section and the eta form to the equivariant case for a fiberwise compact Lie group action and discuss the properties of the equivariant version of eta forms with perturbation.
