Abstract :

Quasi-hereditary algebras occur frequently in representation theory, algebraic geometry and algebraic Lie theory. Their modules with standard filtration form an exact category of particular interest. The main problem to be discussed in these two talks is the structure of this category, which can be described in terms of bocses and of corings. The theory can be applied to an interpretation of Ringel duality and to the problem of existence of exact Borel subalgebras.(Based on joint work with Tomasz Brzezinski, Julian Kuelshammer and Sergiy Ovsienko.)
