Quasi-hereditary algebras and birational morphisms of smooth surfaces.
Following Bezrukavnikov, I will show that a full exceptional
collection in a triangulated category allows to construct a
t-structure whose heart is equivalent to a category of modules over
some quasi-hereditary algebra. I will use this construction to
associate a quasi-hereditary algebra to any birational morphism of
smooth projective surfaces. Then I will describe in more details the
structure of the obtained quasi-hereditary algebras.
