Résume

The double affine Hecke algebra was introduced by Cherednik around 1995 as a tool in his study of Macdonald polynomials. Its degenerate version, called trigonometric double affine Hecke algebra (TDAHA), has also turned out to be linked to different areas, notably to the representation theory of pp-adic groups. Given a root system, the TDAHA HcHc​ depends on a family of complex parameters cc. Given two families of parameters cc and c′c′ whose difference takes integer values, there exists a triangle equivalence between the bounded derived categories of the corresponding TDAHAs, which we call translation functor. The objective of this talk is to explain the construction of this functor. 

This talk will be on Zoom only.
