We resolve the conjecture with positive combinatorial formulas in cases which address the k-Schur expansion of (1) Hall-Littlewood polynomials, proving the q=0 case of the strengthened Macdonald positivity conjecture from [24]; (2) the product of a Schur function and a k-Schur function when the indexing partitions concatenate to a partition, describing a class of Gromov-Witten invariants for the quantum cohomology of complete flag varieties; (3) k-split polynomials, solving a substantial special case of a problem of Broer and Shimozono-Weyman on parabolic Hall-Littlewood polynomials [37]. In addition, we prove the conjecture that the k-Schur functions defined via k-split polynomials [25] agree with those defined in terms of strong tableaux [21].} } } @article {SW, AUTHOR = {Mark Shimozono and Jerzy Weyman}, TITLE = {Graded characters of modules supported in the closure of a nilpotent conjugacy class}, Journal = {Europ.

Combinatorial methods for the explicit construction of free bases for QH[x1 , x2 ,…, xn] as a module over the symmetric polynomials are developed. The methods are developed by studying the action of the symmetric group on the Stanley-Reisner ring of the subset lattice. Some general results are also obtained by studying the action of a Coxeter group on the Stanley-Reisner ring of the corresponding Coxeter complex. In the case of a Weyl group, a purely combinatorial construction of certain invariants first considered by R. Steinberg (Topology14 (1975), 173–177) is obtained. Some applications to representation theory are also included.} } @article{HottaSpringer, AUTHOR = {Hotta, R. and Springer, T.
