Rationality Criteria for Hypersurfaces

An algebraic variety is rational if it admits a birational parametrization by affine space. Stereographic projections of spheres are examples. We still do not know which cubic hypersurfaces are rational! We survey recent results – using classical geometry, Hodge theory, and newer techniques like derived categories –  as well as natural open questions.
