Towards commutator theory for relations. III

Paolo Lipparini

We derive consequences from the existence of a term which satisfies Mal'cev identities (characterizing permutability) modulo two functions F and G from admissible relations to admi…

Intersection properties of relations

Paolo Lipparini

We derive some equalities for relations on the algebra A, under the assumption that every subalgebra of A A is congruence modular.
