Addendum and Corrigendum to: Some homological properties of category 𝒪, V
Abstract
In various special cases, we provide an alternative argument for equivalence between Kostant positivity of some involutions in type A and the conjunction of the categorical Kåhrstr{ö}m's condition for these involutions with indecomposability of the images of the corresponding simple modules in category 𝒪 under projective functors.
