09/09/2019  4:30pm The category O of BernsteinGelfandGelfand and the Schur algebra are interesting and fundamental objects. Following motivation connected to 3dimensional supersymmetric gauge theory, BradenLicataProudfootWebster defined an analogue of category O associated to any hypertoric (aka toric hyperkahler) variety. In joint work with Braden, we use the same geometry to define analogues of the Schur algebra. In fact, we are able to define such an algebra starting from any matroid. In work in progress with Ethan Kowalenko, we extend the construction of BradenLicataProudfootWebster to a matroidal setting as well. In work in progress with Jens Eberhardt, we show that these matroidal Schur algebras and matroidal category O are related to each other via a categorification.
