Dan Burghelea -- Lectures on Witten-Helffer-Sjostrand theory

Abstract: Witten-Helffer-Sj\"ostrand theory} is a considerable addition to the De Rham-Hodge theory for Riemannian manifolds and can serve as a general tool to prove results about comparison of numerical invariants associated to compact manifolds analytically, i.e. by using a Riemannian metric, or combinatorially, i.e by using a triangulation. In this presentation a triangulation, or a partition
