The change of basis coefficients between this family and Schur's $Q$-functions are $q$-analogs of numbers of marked shifted tableaux. These coefficients exhibit many parallel properties to the Kostka-Foulkes polynomials.24 pagesCombinatoricsQuantum Algebra05E05, 05E10A q-analog of Schur's Q-functionstext
