## On rings containing a p-injective maximal left ideal.(English)Zbl 1101.16302

Summary: We investigate rings containing a finitely generated p-injective maximal left ideal. We show that if $$R$$ is a semiprime ring containing a finitely generated p-injective maximal left ideal, then $$R$$ is a left p-injective ring. Using this result we are able to give a new characterization of von Neumann regular rings with nonzero socle.
