Abstract:For a unital ring $ R$, RCFM$ _\alpha (R)$ denotes the ring of row and column finite matrices over $ R$ indexed by $ \alpha$. We give necessary and sufficient structural conditions on RCFM$ _\alpha(R)$ which are equivalent to $ R$ being, respectively, Quasi-Frobenius, left artinian, and left noetherian.
