Abstract

G. Zhitomirskii gave a description of congruence lattices of semilattices in the second-order language. Here we describe finite lattices belonging to this class in terms of properties shared by coatoms (minimal nonidentity elements of a lattice). As a consequence, a characterization of finite semilattices with isomorphic congruence lattices is obtained.
