*讲座内容简介:

For Dirac-type operators acting on two non-compact Riemannian manifolds, if they coincide at infinity and satisfy certain conditions, one can define their relative eta invariant. This is an extension of the idea of eta invariant to non-compact situations. We will talk about its properties and its role in an APS index formula on manifolds with non-compact boundary. We will also discuss its connection with metrics of positive scalar curvature.
