SUMMARY:Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:WANCHUN ROSIE SHEN\, HARVARD UNIVERSITY\n\n\"DU BOIS SINGULARIT
 IES\, RATIONAL SINGULARITIES\, AND BEYOND\"\n\nWe survey some extensions o
 f the classical notions of Du Bois and\nrational singularities\, known as 
 the k-Du Bois and k-rational\nsingularities. By now\, these notions are we
 ll-understood for local\ncomplete intersections (lci). We explain the diff
 iculties beyond the\nlci case\, and propose new definitions in general to 
 make further\nprogress in the theory. This is joint work (in progress) wit
 h Matthew\nSatriano\, Sridhar Venkatesh and Anh Duc Vo.\n\nMC 5417
