SAGBI bases and Degeneration of Spherical Varieties to Toric Varieties

Kiumars Kaveh

Let X \subset Proj(V) be a projective spherical G-variety, where V is a finite dimensional G-module and G = SP(2n, C). In this paper, we show that X can be deformed, by a flat defo…

Fixed Points of Torus Action and Cohomology Ring of Toric Varieties

Kiumars Kaveh

Let X be a smooth simplicial toric variety. Let Z be the set of T-fixed points of X. We construct a filtration for A(Z), the ring of complex-valued functions on Z, such that Gr A(Z…
