Lattice extensions of Hecke algebras

speaker: Ivan Marin (Université de Picardie-Jules Verne)

abstract: We shall first recall the construction of Hecke algebras associated to a (finite) Coxeter group, and then more generally to a complex reflection group. We then introduce extensions of them, which are related to natural actions of the reflection group on lattices, and describe their structure.
