Ding projective modules over Morita context rings

Abstract–

Let ${\Delta }_{(0,0)}=(\begin{array}{cc}A\hfill & {}_A{N}_B\hfill \\ {}_B{M}_A\hfill & B\hfill \end{array})$ be a Morita context ring with zero bimodule homomorphisms. We give sufficient conditions for modules over ${\Delta }_{(0,0)}$ to be Ding projective.
