Abstract:
Springer fibers are a family of varieties that have remarkable connections to combinatorics and representation theory. Springer used them to geometrically construct all of the irreducible representations of the symmetric group (Specht modules). Moreover, they give a geometric meaning to Hall-Littlewood symmetric functions. In this talk, I will introduce a generalization of Springer fibers called $\Delta$-Springer varieties, a special case of which gives a new geometric meaning to the expression in the Delta Conjecture at t=0. We’ll then use these varieties to geometrically construct induced versions of the Specht modules. This is joint work with Jake Levinson and Alexander Woo.
