Parameter spaces of Schubert varieties in hyperplane sections of Grassmannians
Linear sections of Grassmannians provide important examples of varieties. The geometry of these linear sections is closely tied to the spaces of Schubert varieties contained in them. In this paper, we describe the spaces ...
Singularities of Generalized Richardson Varieties
(Taylor and Francis, 2012-04)
Richardson varieties play an important role in intersection theory and in the geometric interpretation of the Littlewood-Richardson Rule for ag varieties. We discuss three natural generalizations of Richardson varieties ...
