DESCRIPTION:It was proved by Gabber in the early 1980's that R\\Psi commut
es with duality\, and that R\\Phi preserves perversity up to shift. It had
been in the folklore since then that this last result was in fact a conse
quence of a finer one\, namely the compatibility of R\\Phi with duality. I
n this talk I'll give a proof of this\, using a method explained to me by
A. Beilinson.\n\nhttps://indico.math.cnrs.fr/event/1761/
