ON THE GENERAL THEORY OF RELATIONALMORPHISMS
Wyllis Bandler, Ladislav Kohout · International Journal of General Systems · 1986
Many diverse problems of compatibility of structures can be unified by generalizing tjie concept of a homomorphism. The paper introduces generalized proteromorphisms and amphimorphisms, forward and backward compatibility of relations, as well as other new useful concepts. These generalizations find application in solving relational equalions, investigation of compatibility of systems and data structures, in examining faithfulness of representations of knowledge structures in knowledge-based systems, in semiotics and elsewhere.
