A Vanishing Theorem for Varieties with Finitely Many Solvable Group Orbits
Yiyu Wang
We reprove and generalize the result that the intersection cohomology groups of a toric variety with coefficient in a nontrivial rank one local system vanish. We prove a similar va…

Ramified cover of varieties with nef cotangent bundle
Yiyu Wang
We construct examples to show that having nef cotangent bundle is not preserved under finite ramified covers. Our examples also show that a projective manifold with Stein universal…
