Cylindric versions of specialised Macdonald functions and a deformed Verlinde algebra
C Korff - Communications in Mathematical Physics, 2013 - Springer
We define cylindric versions of skew Macdonald functions P λ/μ (q, t) for the special cases q=
0 or t= 0. Fixing two integers n> 2 and k> 0 we shift the skew diagram λ/μ, viewed as a …

From Macdonald polynomials to a charge statistic beyond type A
C Lenart - Journal of Combinatorial Theory, Series A, 2012 - Elsevier
The charge is an intricate statistic on words, due to Lascoux and Schützenberger, which
gives positive combinatorial formulas for Lusztigʼs t-analogue of weight multiplicities and …
