A criterion for associated bundles and the weak Beauville--Bogomolov decomposition

Yang Zhang

We give a criterion for a fibration to be an associated fibre bundle. As an application, we show that, under suitable singularity and Cartier-index assumptions, any surjective fibr…

Classification of irreducible unitary modules over $u (p, q ∣ n)$

Mark D. Gould, Artem Pulemotov, Jorgen Rasmussen +1

We classify all irreducible highest-weight unitary modules over the non-compact real form $u (p, q ∣ n)$ of the general linear Lie superalgebra $gl_{p + q ∣ n}$ . The…

Einstein metrics on homogeneous superspaces

Yang Zhang, Mark D. Gould, Artem Pulemotov +1

This paper initiates the study of the Einstein equation on homogeneous supermanifolds. First, we produce explicit curvature formulas for graded Riemannian metrics on these spaces.…
