报告摘要：Given a field k, a group G and a subgroup H of G, we consider relations on representation dimensions of the group algebras kG and kH. This is done by applications of Frobenius extensions. In particular, we show that, for any subgroup H of a finite nilpotent group G, if [G:H] is invertible in the field, then the representation dimensions of kG and kH are the same.
