Derived equivalences for symmetric groups and sl(2)-categorification
We define and study sl2-categorifications on abelian categories. We show in particular that there is a self-derived (even homotopy) equivalence cate-gorifying the adjoint action of the simple reflection. We construct categorifica-tions for blocks of symmetric groups and deduce that two blocks are sp...
