Horaire14:00 à 15:00
RésumeQuasi-hereditary algebras and their infinite analogues, highest weight categories, appear frequently in many areas of representation theory. In joint work with S. Koenig and S. Ovsienko, we showed that every quasi-hereditary algebra can up to Morita equivalence be obtained as the dual of a coring object in the tensor category of bimodules over a directed algebra, the exact Borel subalgebra. Under an additional assumption, the exact Borel subalgebra as well as the coring object are in fact unique up to isomorphism. This is joint work with V. Miemietz.
