Morita contexts, ideals, and congruences for semirings with local units; pp. 252–259

Laur Tooming

We consider Morita contexts for semirings that have certain local units but not necessarily an identity element. We show that the existence of a Morita context with unitary bisemimodules and surjective maps implies that the two semirings involved have isomorphic quantales of ideals and lattices of congruences.
