Entropy of affine permutations and universality of affine atomic lengths

Nathan Chapelier-Laget, Thomas Gerber, Nicolas Jacon +1

We introduce and study the notion of entropy of affine permutations and prove that it coincides with the atomic length associated with the sum of the fundamental weights for a type…

The asymptotic Plancherel formula and Lusztig's asymptotic algebra for $A ~_{n}$

The aim of this paper is to give a new explicit construction of Lusztig's asymptotic algebra in affine type $A$ . To do so, we construct a balanced system of cell modules,…
