Title: Supercentralisers for realisations of osp(1|2) and Howe duality
Abstract: In this talk, we consider the orthosymplectic Lie superalgebra osp(1|2). For a realisation of osp(1|2) in a superalgebra, we show that its supercentraliser can be obtained by means of projection operators. We then apply this technique to the context of Howe duality, where we have a realisation of osp(1|2) containing the Dirac operator. Next, we consider deformations, involving a rational Cherednik algebra associated with a real reflection group, that preserve the osp(1|2) realisation and again study its supercentralizer.
