Crepant resolutions of projectivised
nilpotent orbits
Abstract
The
projectivised nilpotent orbit closure (in a complex
semi-simple Lie algebra) carries a natural contact structure. It turns out that
for such varieties a crepant resolution is a
resolution on which the contact structure extends to the whole variety. In
this talk, we will determine when such a resolution exists, and in the case of
several different ones, we will compare them by describing their movable cones.
