Arithmetic Geometry Seminar - Raymond Cheng
Title: q-bic Hypersurfaces
Speaker: Raymond Cheng - Columbia University
Abstract: The geometry of Fano hypersurfaces, especially over the complex numbers, is a classical and rich subject. Many of their remarkable features may be understood through their abundance of low degree rational curves. This talk will discuss a class of hypersurfaces in positive characteristic p which exhibits geometric properties, such as unirationality and smoothness of schemes of linear spaces, classically expected only of quadrics and cubics. These phenomena are related to the modular representation theory of general linear groups.
