Total rank of Tor groups
Abstract:
I will report on ongoing joint work with Keller VandeBogert and Jerzy Weyman on the total rank of the Tor groups of modules over polynomial rings that arise from representations of Lie algebras. This work is motivated by the problem of understanding lower bounds on the total rank of free complexes with finite length homology and also the problem of computing syzygies of nilpotent orbit closures.
