A Combinatorial Description of Blocks in ( ,Λ) Associated with sl(2)-Induction

We study the category ( ,Λ), where Λ is an admissible category of dense weight sl(2)-modules. We give a combinatorial description of projectively stratified algebras, arising from ( ,Λ) and prove a double centralizer property. Moreover, we determine the characters of tilting modules in ( ,Λ) and prove that the finite-dimensional algebra associated with the principal block of our ( ,Λ) is its own Ringel dual.
