    Centralisers in braid groups.

    Friday 10th November, 12-1pm, Carslaw 275.

    We show that the centraliser in the classical braid group of a regular element in the sense of Springer is itself a braid group associated to some complex reflection group. (This is joint work with D. Bessis and J. Michel.)
