Atomary tolerances on finite algebras

Bohdan Zelinka (1996)

Mathematica Bohemica

Similarity:

A tolerance on an algebra is defined similarly to a congruence, only the requirement of transitivity is omitted. The paper studies a special type of tolerance, namely atomary tolerances. They exist on every finite algebra.
