The S_n action on the homology groups of M_{0,n}-bar

Abstract: The moduli space M_{0,n}-bar is a compactification of the space of configurations of n points on P^1. The symmetric group on n letters acts on M_{0,n}-bar, and thus on its (co-)homology groups. I will introduce M_{0,n}-bar, its (co-)homology groups, and the S_n action. This talk includes joint work with Rob Silversmith.

SFU NT-AG seminar

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
