Skeletons of quasivarieties with the Fraser-Horn property. (Q1771854)

Skeletons of varieties and Cartesian skeletons as well as isomorphism types of algebras were introduced by the author in previous papers. Most results on skeletons of congruence-distributive varieties have been proved by the author. In this paper he generalizes these results to quasivarieties of algebras satisfying the Fraser-Horn property (decomposition of congruences on direct products).
