摘 要：

For an abelian category A, we establish the relation between its derived and extension dimensions. Then for an artin algebra λ, we give the upper bounds of the extension dimension of λ in terms of the radical layer length of λ and certain relative projective (or injective) dimension of some simple λ-modules, from which some new upper bounds of the derived dimension of λ are induced. This is a joint work with Junling Zheng.
