A Reciprocity Result for Projective Indecomposable Modules of Cellular Algebras and BGG Algebras
Journal of Lie theory, Tome 22 (2012) no. 4, pp. 1065-1073
We show that an adaptation of Landrock's Lemma for symmetric algebras also holds for cellular algebras and BGG algebras. This is a result relating the radical layers of any two projective modules. As a corollary we deduce that BGG reciprocity respects Loewy structure.
