Bigrassmannian permutations and Verma modules
Hankyung Ko, Volodymyr Mazorchuk, Rafael Mrđen
We show that bigrassmannian permutations determine the socle of the cokernel of an inclusion of Verma modules in type . All such socular constituents turn out to be indexed by W…
Some homological properties of category , V
Hankyung Ko, Volodymyr Mazorchuk, Rafael Mrđen
We compute projective dimension of translated simple modules in the regular block of the BGG category in terms of Kazhdan-Lusztig combinatorics. This allows us to det…
Adjunction in the absence of identity
Hankyung Ko, Volodymyr Mazorchuk, Xiaoting Zhang
We develop a bicategorical setup in which one can speak about adjoint 1-morphisms even in the absence of genuine identity 1-morphisms. We also investigate which part of 2-represent…
