Đề tài " Stability conditions on triangulated categories "

This paper introduces the notion of a stability condition on a triangulated category. The motivation comes from the study of Dirichlet branes in string theory, and especially from . Douglas’s work on Π-stability. From a mathematical point of view, the most interesting feature of the definition is that the set of stability conditions Stab(D) on a fixed category D has a natural topology, thus defining a new invariant of triangulated categories. In a separate article [6] I give a detailed description of this space of stability conditions in the case that D is the bounded derived category of coherent.
