Author: Rafael Mrđen Mathematical Communications 25(2020), 13–34. https://www.mathos.unios.hr/mc/index.php/mc/article/view/3149 Abstract: Using the Penrose transform, we construct analogues of the BGG (Bernstein-Gelfand-Gelfand) resolutions in certain singular infinitesimal characters, in the holomorphic geometric setting, over the Lagrangian Grassmannian. We prove the exactness of the constructed complex over the big affine cell.

Here we consider conformal embeddings in simple affine vertex superalgebra where is a basic classical simple Lie superalgebra. Let be the subalgebra of generated […]

Let V be a vertex operator algebra, g an automorphism of order p. Let W be an irreducible weak V–module such that […]
Authors: Dražen Adamović, Veronika Pedić Journal of Mathematical Physics 60, 081701 (2019); https://doi.org/10.1063/1.5098128 Abstract: In vertex algebra theory, fusion rules are described as the dimension of the vector space of intertwining operators between three irreducible modules. We describe fusion rules in the category of weight modules for the Weyl vertex algebra. This way, […]
