An involution in search of a functor

We define an involution Phi on multi-partitions which generalizes the well-known Mullineux involution on e-regular partitions. The construction of Phi suggests that it should arise from a special kind of derived equivalence, called a perverse equivalence, between particular categories of representations whose Grothendieck groups have bases consisting of multi-partitions. We will explain how to identify this functor, as well as the relation of Phi to what are called wall-crossing functors. This is work in progress with Thomas Gerber and Nicolas Jacon.
