Strongly Gorenstein-injective modules over Morita rings.

In this paper, we consider Morita rings with zero bimodule homomorphisms. We establish necessary and sufficient conditions for all strongly complete injective resolutions over a Morita ring Δ (0 , 0) = A A N B B M A B . We also obtain necessary and sufficient conditions for all strongly Gorenstein-injective modules over Δ (0 , 0) . [ABSTRACT FROM AUTHOR]
