Abstract

By a nearlattice is meant a join-semilattice where every principal filter is a lattice with respect to the induced order. The aim of our paper is to show for which nearlattice 𝒮 and its element c the mapping ϕ c ( x ) = x c , x p c is a (surjective, injective) homomorphism of 𝒮 into [ c ) × ( c ] .
