Congruences in ordered sets and LU compatible equivalences. (English). Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica, vol. 48 (2009), issue 1, pp. 153-156
MSC: 06A06, 06B10 | MR 2641955 | Zbl 1203.06001
Keywords:
Ordered set; morphism; $LU$ compatible equivalence
Summary:
A concept of equivalence preserving upper and lower bounds in a poset $P$ is introduced. If $P$ is a lattice, this concept coincides with the notion of lattice congruence.
