Irreducible components of two-column $Δ$ -Springer fibers

Joshua P. Connor, Sean T. Griffin, Kavish A. Purohit

The $Δ$ -Springer fibers $Y_{n, λ, s}$ , introduced by Levinson, Woo, and the second author, generalize Springer fibers for $GL_{n} (C)$ and give a geometric interpretat…

A combinatorial skewing formula for the Rise Delta Theorem

Maria Gillespie, Eugene Gorsky, Sean T. Griffin

We prove that the symmetric function $Δ_{e_{k - 1}}^{'} e_{n}$ appearing in the Delta Conjecture can be obtained from the symmetric function in the Rational Shuffle Theorem by applying a S…

Cocharge and skewing formulas for $Δ$ -Springer modules and the Delta Conjecture

Maria Gillespie, Sean T. Griffin

We prove that $ω Δ_{e_{k}}^{'} e_{n} ∣_{t = 0}$ , the symmetric function in the Delta Conjecture at $t = 0$ , is a skewing operator applied to a Hall-Littlewood polynomial, and generalize this f…
