Rationality does not specialize among terminal fourfolds

Alexander Perry

Vol. 11 (2017), No. 9, 2193–2196
Abstract

We show that rationality does not specialize in flat projective families of complex fourfolds with terminal singularities. This answers a question of Totaro, who established the corresponding result in dimensions greater than 4.

Keywords
