NT seminar TODAY: Tangli Ge

[Bianca Viray]

Hi everyone,

Our speaker today is Tangli Ge from Princeton University and he will be speaking on Exceptional loci on abelian varieties (abstract below) at 11am in PDL C-401. As usual, we will go to lunch with the speaker after the talk.

Abstract: The talk will be about a generalization of the Ueno locus for subvarieties of abelian varieties, the so-called anomalous locus, which naturally appears in the setting of unlikely intersections. In particular, the anomalous locus is known to be Zariski closed by Rémond. I will show that there is a generalized Ueno fibration. In the family setting, I will explain the Zariski closedness of fiber-wise anomalous locus in characteristic 0, and of fiber-wise Ueno locus in arbitrary characteristic.
