  This paper is a following to math.RT/0410454. For a finite group of Lie type
we study the endomorphisms, commuting with the group action, of a
Deligne-Lusztig variety associated to a regular element of the Weyl group. We
state some general conjectures, in particular that the endomorphism algebra
induced on the cohomology is a cyclotomic Hecke algebra, and prove them in some
cases. On the way we also prove results on centralizers in braid groups.
