Coarse geometry is a study of metric spaces from "large scale view points". I am intersterd in the relation between coarse geometric properties of metric spaces and topological properties of their Higson conronae. Recently, I am studying coarse Baum-Connes conjecture for relatively hyperbolic groups.
Groebner basis enables us to do symbolic calculation by computers. I have studied the ring structure of cohomology of some homogeneous spaces.
