Algebraic Geometry Seminar

Existence of Twisted Symmetric Differentials and the Geometry of Projective Subvarieties

Speaker: Christopher Langdon, University of Miami

Location: Warren Weaver Hall 1314

Date: Tuesday, November 8, 2016, 3:10 p.m.


I will discuss the relation between sections of the m-th symmetric power of the twisted cotangent bundle ΩX(1) on a projective subvariety X of low codimension and the equations defining X. In particular, I will give an explicit description of these sections in terms of the quadrics defining X when X is a complete intersection of low codimension.
