SUMMARY:Pure subrings of Du Bois singularities are Du Bois singularities Note the unusual time!
DESCRIPTION:Speaker: Takumi Murayama\, Purdue University\n\nLet \(R \rightarrow S\) be a pure map of rings. If \(S\) is regular, then it is known that \(R\) has rational singularities, and hence is Cohen-Macaulay. This result applies in particular to inclusions of rings of invariants by linearly reductive groups, split maps, and faithfully flat maps. In this …
