The atomic Leibniz rule
Ben Elias, Hankyung Ko, Nicolas Libedinsky +1
The Demazure operator associated to a simple reflection satisfies the twisted Leibniz rule. In this paper we introduce a generalization of the twisted Leibniz rule for the Demazure…
Singular Light Leaves
Ben Elias, Hankyung Ko, Nicolas Libedinsky +1
For any Coxeter system we introduce the concept of singular light leaves, answering a question of Williamson raised in 2008. They provide a combinatorial basis for Hom spaces betwe…
Demazure operators for double cosets
Ben Elias, Hankyung Ko, Nicolas Libedinsky +1
For any Coxeter system, and any double coset for two standard parabolic subgroups, we introduce a Demazure operator. These operators form a basis for morphism spaces in a category…
IntroSurvey of representation theory
Nicolas Libedinsky
There could be thousands of Introductions/Surveys of representation theory, given that it is an enormous field. This is just one of them, quite personal and informal. It has an inc…
Combinatorial invariance conjecture for
Gaston Burrull, Nicolas Libedinsky, David Plaza
The combinatorial invariance conjecture (due independently to G. Lusztig and M. Dyer) predicts that if and are isomorphic Bruhat posets (of possibly different Cox…
Pre-canonical bases on affine Hecke algebras
Nicolas Libedinsky, Leonardo Patimo, David Plaza
For any affine Weyl group, we introduce the pre-canonical bases. They are a set of bases (where is the height of the highest root) of the…
