İstanbul Matematiksel Bilimler Merkezi SeminerleriRigid toric matrix Schubert varieties İrem Portakal In this talk, we introduce the usual torus action on matrix Schubert varieties. In the toric case we show that these varieties arise from a bipartite graph. We study the first order deformations of toric matrix Schubert varieties and we prove that it is rigid if and only if the three-dimensional faces of its associated (edge) cone are all simplicial.
