Title: Eta invariants for manifolds with cone points

Abstract:

The "signature" or eta invariant originally appeared as the boundary
correction term of the famous index formula of Atiyah, Patodi, and Singer,
but since this seminal paper, the study of the eta invariant has taken
off with a life of its own. In this talk, I will give a very gentle
introduction to the Atiyah-Patodi-Singer index formula, then I'll focus
on the eta invariant and some of its properties, but for the bulk of the
talk I'll discuss some remarkable properties of manifolds that have cone
points and their eta invariants.
