Topological Gysin Coherence for Algebraic Characteristic Classes of Singular Spaces

Markus Banagl, Jörg Schürmann, Dominik J. Wrazidlo

Brasselet, the second author and Yokura introduced Hodge-theoretic Hirzebruch-type characteristic classes , and conjectured that they are equal to the Goresky-MacPher…

A new generic vanishing theorem on homogeneous varieties and the positivity conjecture for triple intersections of Schubert cells

Jörg Schürmann, Connor Simpson, Botong Wang

In this paper we prove a new generic vanishing theorem for a complete homogeneous variety with respect to an action of a connected algebraic group. Let be loc…
