The fixed locus of a symplectic involution on a hyperkahler 4-fold of Kummer type

Abstract: In this talk I will discuss work in progress joint with Sarah Frei on symplectic involutions of hyperkahler manifolds of Kummer type. The fixed loci of these involutions correspond to cohomology classes and have very interesting properties. The talk will focus on the geometry of such a fixed locus on a particular 4-fold.

Series comments: The Number Theory and Algebraic Geometry (NT-AG) seminar is a research seminar dedicated to topics related to number theory and algebraic geometry hosted by the NT-AG group (Nils Bruin, Imin Chen, Stephen Choi, Katrina Honigs, Nathan Ilten, Marni Mishna).

We acknowledge the support of PIMS, NSERC, and SFU.

For Fall 2025, the organizers are Katrina Honigs and Peter McDonald.

We normally meet in-person in the indicated room. For online editions, we use Zoom and distribute the link through the mailing list. If you wish to be put on the mailing list, please subscribe to ntag-external using lists.sfu.ca
