Rationality conjecture for varieties with Du Bois divisors
Rationality conjecture for varieties with Du Bois divisors
Let be a reduced scheme of finite type over a field of characteristic zero, and let be a Cartier divisor with Du Bois singularities. Assume that has rational singularities. Rationality conjecture for Du Bois divisors. Then has rational singularities; in particular, is Cohen–Macaulay. This conjecture generalizes the known result in which is assumed smooth, and is motivated by the relationship between rational and Du Bois singularities. Its resolution status is not given in the supplied text.
