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

Maria Gillespie, Sean T. Griffin

We prove that $\omega {\Delta }_{e_k}^{\prime }{e}_n{|}_{t=0}$, the symmetric function in the Delta Conjecture at $t=0$, is a skewing operator applied to a Hall-Littlewood polynomial, and generalize this f…
