Abstract

This paper is a short survey of classical and recent results on rationality or stable rationality for smooth projective varieties. We describe (or reinterpret in a geometric form) cohomological or Chow theoretic criteria for stable rationality, like the triviality of unramified cohomology or the universal triviality of the Chow group of zero cycles, and show that they are effective on examples.
