Title: Gysin maps, duality, and Schubert classes
Abstract: We establish a Gysin formula for Kempf-Laksov flag
bundles and prove a duality formula for Grassmann bundles.
We then combine them to study Schubert bundles, their
push-forwards and fundamental classes.
This is a joint work with Lionel Darondeau.
