DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCGEN/11/">R
 igid toric matrix Schubert varieties</a>\nby Irem Portakal (Otto von Gueri
 cke University Magdeburg) as part of UCGEN - Uluslararası Cebirsel GEomet
 ri Neşesi\n\n\nAbstract\nIn this talk\, we introduce the usual torus acti
 on on matrix Schubert varieties. In the toric case we show that these vari
 eties 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 on
 ly if the three-dimensional faces of its associated (edge) cone are all si
 mplicial.\n
