An Application of Collapsing Levels to the Representation Theory of Affine Vertex Algebras

Friday October 26th, 2018 Rafael Mrđen 0

Authors: Dražen Adamović, Victor G Kac, Pierluigi Möseneder Frajria, Paolo Papi, Ozren Perše International Mathematics Research Notices, rny237, https://doi.org/10.1093/imrn/rny237 Abstract: We discover a large class of simple affine vertex algebras , associated to basic Lie superalgebras  at non-admissible collapsing levels , having exactly one irreducible -locally finite module in the category . In the case when  is […]

Authors: Denis Husadžić, Rafael Mrđen Journal of Lie Theory 28 (2018), No. 4, 1149–1164 http://www.heldermann.de/JLT/JLT28/JLT284/jlt28054.htm (preprint: https://arxiv.org/abs/1803.10497) Abstract: We construct exact sequences of invariant differential operators acting on sections of certain homogeneous vector bundles in singular infinitesimal character, over the isotropic 2-Grassmannian. This space is equal to G/P, where G is Sp(2n,C), and P its standard parabolic subgroup having […]
