Authors: Volodymyr Mazorchuk, Rafael Mrđen Journal of Pure and Applied Algebra 224 (2020), Issue 12, 106449 https://doi.org/10.1016/j.jpaa.2020.106449 Abstract: Using translation from the regular block, we construct and analyze properties of BGG complexes in singular blocks of BGG category . We provide criteria, in terms of the Kazhdan-Lusztig-Vogan polynomials, for such complexes to be exact. […]
