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