2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/70817We state a conjecture which gives a combinatorial parametrization of the irreducible tempered representations with real central character of a graded Hecke algebra with unequal labels, associated to a root sytem of type B or C. This conjecture is based on a combinatorial generalization of the Springer correspondence in the classical (equal label) case. In particular, the described modules turn out to have a natural grading for the action of W_0, and are completely determined by their central character together with the W_0-representation in the top degree. This latter is an irreducible W_0-character which we call Springer correspondent.59 pages, 15 figuresCombinatoricsRepresentation Theory20C08, 05E99Generalized Green functions and graded Hecke algebrastext
