Abstract: | A survey of results on congruence-distributive varieties of algebras, concentrated on two directions: 1) the construction of algebras of congruence-distributive varieties and the structure of the variety itself, 2) questions connected with formalized (equational, elementary, etc.) theories of such varieties. In addition the survey includes papers connected with congruence-distributive varieties of algebras reviewed in RZh Matematika during the period 1976–1985.Translated from Itogi Nauki i Tekhniki, Seriya Algebra, Topologiya, Geometriya, Vol. 26, pp. 45–83, 1988. |
