We show that it is equivalent to the derived category of finitely generated modules over the path algebra of the corresponding Dynkin quiver. Also, we discuss a special stability condition for the triangulated category in the sense of T. Bridgeland, which is naturally defined by the grading.v2: typos corrected, added an appendix by K.UedaAlgebraic GeometryHigh Energy Physics - TheoryRepresentation Theorytext
