Brendan Hassett, Recent Progress and Questions on Stable Rationality
on-line
Algebraic Geometry Seminar
Speaker Brendan Hassett ICERM / Brown Univ. A complex variety X is rational if its field of meromorphic functions is isomorphic to C(t1, ..., td), the function field of projective space Pd. It is stably rational if X × Pm is rational for some m. Topological and complex invariants give criteria for whether …
