Abstract

The complexity of the simple and the Kac modules over the general linear Lie superalgebra gl(mn)\mathfrak{gl}(m|n) of type AA was computed by Boe, Kujawa, and Nakano in 2012. A natural continuation to their work is computing the complexity of the same family of modules over the ortho-symplectic Lie superalgebra osp(22n)\mathfrak{osp}(2|2n) of type CC. The two Lie superalgebras are both of Type I which will result in similar computations. In fact, our geometric interpretation of the complexity agrees with theirs. We also compute a categorical invariant, z-complexity, introduced in Boe et al., and we interpret this invariant geometrically in terms of a specific detecting subsuperalgebra. In addition, we compute the complexity and the z-complexity of the simple modules over the Type II Lie superalgebras osp(32)\mathfrak{osp}(3|2), D(2,1;α)D(2,1;\alpha), G(3)G(3), and F(4)F(4).
