Title: Reductions of abelian surfaces over global function fields
Speaker: Yunqing Tang
Speaker Info: Princeton University
Brief Description:
Special Note:

For a non-isotrivial ordinary abelian surface $A$ over a global function field, under mild assumptions, we prove that there are infinitely many places modulo which $A$ is geometrically isogenous to the product of two elliptic curves. This result can be viewed as a generalization of a theorem of Chai and Oort. This is joint work with Davesh Maulik and Ananth Shankar.
