The following problem arose in a conversation with Abraham Zaks: “Suppose R is an associative ring with identity such that every finitely generated left ideal is generated by idempotents. Is R von-Neumann regular?” In the literature the “s” in “idempotents” is missing, and is replaced by “an idempotent”. The answer is, “Yes!”
Conditions on elements, invalid proof, von Neumann regular rings and generalizations (associative algebraic aspects), idempotents, finitely generated left ideal, von Neumann regular ring
