In general, Gorenstein projective and Gorenstein flat modules have no obvious relations. But I find that nobody discusses Gorenstein flat modules when the ring is an Artin algebra. So I believe that they are the same thing under this condition. Can anyone give me an explanation of this thing? Thank you very much!

Over an Artin algebra, does Gorenstein projective and Gorenstein flat modules coincides?
