Universal Gysin formulas for flag bundles
Universal Gysin formulas for flag bundles
We give push-forward formulas for all flag bundles of types [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text]. The formulas (and also the proofs) involve only Segre classes of the original vector bundles and characteristic classes of universal bundles. As an application, we provide new determinantal …
