Congruence-distributive varieties of algebras. (Russian) Zbl 0679.08004
Congruence-distributive varieties of algebras are subsets of the set of congruence-modular varieties as well as subsets of the Abelian varieties. These two subsets are independent. Congruence-distributive varieties include, for example, varieties of lattices, lattice-ordered groups, and other similar algebras, and varieties generated by primal algebras.
This survey of results on congruence-distributive varieties of algebras consists of 1) the construction of algebras of a congruence-distributive variety, and the construction of the variety itself, 2) questions associated with the formalized theories of these varieties. In addition the survey includes results from works connected with congruence- distributive varieties reviewed in R. Zh. in the section of Universal Algebra in the years 1976-1985.
