Abstract

In 2000, Kadell gave an orthogonality conjecture for a symmetric function generalization of the qq-Dyson constant term identity or the Zeilberger--Bressoud qq-Dyson theorem. The non-zero part of Kadell's orthogonality conjecture is a constant term identity indexed by a weak composition v=(v1,,vn)v=(v_1,\dots,v_n) in the case when only one vi0v_i\neq 0. This conjecture was first proved by K\'{a}rolyi, Lascoux and Warnaar in 2015. They further formulated a closed-form expression for the above mentioned constant term in the case when all the parts of vv are distinct. Recently we obtain a recursion for this constant term provided that the largest part of vv occurs with multiplicity one in vv. In this paper, we generalize our previous result to all compositions vv.
