Generalizations of the Chern-Hirzebruch-Serre formula in complex algebraic geometry
Abstract: The Chern-Hirzebruch-Serre signature theorem asserts that in the category of closed oriented
manifolds the topological signature is multiplicative in fibrations with trivial monodromy
action. In this talk I will survey various extensions of this result to the singular setting,
including the so-called ``stratified multiplicative property'' for Hodge invariants of complex algebraic varieties. This is joint work with S. Cappell, A. Libgober and J. Shaneson.
