When is a product of EP elements again EP?
Year: 2026
Type: article
Abstract: In this paper, we give necessary and sufficient conditions for a product of EP elements to be EP, in Dedekind-finite ∗-rings. The proofs rely on descriptions of Morita contexts (via Peirce matrix forms) as corner rings of 2×2 matrix rings.
