Závislosti mezi kongruenčními třídami se studují pomocí vhodných zobecnění pojmů regularita, n-permutabilita, modularita a koherence. (cs)
General dependences between congruence classes are investigated by considering suitable generalizations of the notion of regularity, n-permutability, congruence modularity and coherence.
