An algorithm for computing the canonical bases of higher-level q-deformed Fock spaces

Xavier Yvonne

We derive a straightening-free algorithm that computes the canonical bases of any higher-level q-deformed Fock space.

From triangulated categories to cluster algebras

Philippe Caldero, Bernhard Keller

The cluster category is a triangulated category introduced for its combinatorial similarities with cluster algebras. We prove that a cluster algebra A of finite type can be realize…

Positivity results for the Hecke algebras of non-crystallographic finite Coxeter groups

Fokko Du Cloux

This paper is a report on a computer check of some positivity properties of the Hecke algebra in type H4, including the non-negativity of the coefficients of the structure constant…

Relative Kazhdan--Lusztig cells

Meinolf Geck

In this paper, we study the Kazhdan--Lusztig cells of a Coxeter group in a ``relative'' setting, with respect to a parabolic subgroup . This relies on a factor…

Kazhdan--Lusztig cells and the Murphy basis

Meinolf Geck

Let be the Iwahori--Hecke algebra associated with , the symmetric group on symbols. This algebra has two important bases: the Kazhdan--Lusztig basis and the Murphy bas…

Geometric lifting of the canonical basis and semitoric degenerations of Richardson varieties

Sophie Morier-Genoud

In the sl\_n case, A. Berenstein and A. Zelevinsky studied the Schützenberger involution in terms of Lusztig's canonical basis, [3]. We generalize their construction and formulas f…
