Smooth weighted hypersurfaces that are not stably rational
arXiv:1709.07748
Abstract
We prove the failure of stable rationality for many smooth well formed weighted hypersurfaces of dimension at least 3. It is in particular proved that a very general smooth well formed Fano weighted hypersurface of index one is not stably rational.
