SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Shioda's conjecture on unirationality
DESCRIPTION:In characteristic zero\, Castelnuovo proved that a unirational surface is rational. In positive characteristic\, this fails. We discuss the plethora of non-rational\, often general-type\, surfaces that are unirational in positive characteristic. In 1977\, Shioda conjectured that these surfaces are classified by a cohomological property: supersingularity. I will demonstrate a counterexample to this conjecture. We will need a new obstruction that uses ideas from the study of hyperbolicity.
