Log canonical and Du Bois singularities
Abstract: I will discuss recent joint work with S\'{a}ndor Kov\'{a}cs and Karen
Smith. I will describe a simple new Kempf-like characterization of Du Bois
singularities in the normal Cohen-Macaulay case and explain how it can be
used to show that Cohen-Macaulay (semi-)log canonical singularities are Du
Bois, a conjecture of Koll\'{a}r. As a corollary, we obtain generalizations to
Kodaira-type vanishing theorems.
