Abstract:

We use a weight-preserving, sign-reversing involution to find a combinatorial expansion of $\Delta _{e_k} e_n$ at in terms of the elementary symmetric function basis. We then use a weight-preserving bijection to prove the Delta Conjecture of Haglund, Remmel, and Wilson at . The method of proof provides a variety of structures which can compute the inner product of $\Delta _{e_k} e_n\vert _{q=1}$ with any symmetric function.
