Modified Macdonald polynomials and mu-Mahonian statistics
Emma Yu Jin, Xiaowei Lin
The Haglund--Haiman--Loehr theorem provides the following combinatorial formula for the modified Macdonald polynomials: $$\tilde{H}_μ(X;q,t)=\sum_{Ï: μ\rightarrow \mathbb{P}}x^Ï…

The monomial expansions of modified Macdonald polynomials
Emma Yu Jin, Xiaowei Lin
We discover a family of sixteen statistics on fillings of any given Young diagram and prove new combinatorial formulas for modified Macdonald polynomials, that is, $$\tilde{H}_…
