Positivity of Pre-Canonical Bases for Spherical Hecke Algebras
David Plaza, Yamil Sagurie
We introduce a new algorithm for computing Kostka-Foulkes polynomials. It arises from a combinatorial procedure that computes the transition coefficients between successive pre-can…
A differential characterization of volume polynomials of permutohedra
Tristram Bogart, Federico Castillo, Damián de la Fuente +1
We study a graded vector space of polynomials associated to a square matrix, defined by a finite difference condition along the rows. We show this space coincides with one defined…
Type Temperley-Lieb algebra quotients and Catalan combinatorics
Sadek Al Harbat, Camilo González, David Plaza
We study some algebraic and combinatorial features of two algebras that arise as quotients of Temperley-Lieb algebras of type , namely, the two-boundary Temperley-Lieb a…
Diagrammatics for Kazhdan-Lusztig R-polynomials
David Plaza
Let be an arbitrary Coxeter system. We introduce a family of polynomials, , indexed by pairs formed by an…
