Source algebra equivalences for blocks of finite general linear groups over a fixed field Radha Kessar Abstract. T. Jost proved that Donovan's conjecture holds for the unipotent blocks of the finite general linear groups over a fixed field. In this paper, we show that the Morita equivalences exhibited by Jost are in fact equivalences between the source algebras of the corresponding blocks, and thus Puig's conjecture holds for the unipotent blocks of finite general linear groups over a fixed field.
