Popis: | We show that the transition matrix from the standard basis to the web basis for a Specht module of the Hecke algebra is unitriangular and satisfies a strong positivity property whenever the Specht module is labeled by a partition with at most two parts. This generalizes results of Russell--Tymoczko and Rhoades. Comment: 24 pages, improved exposition and additional details, updated first author's contact information and references, to appear in IMRN |
