The Topology on a Complete Semilattice

Authors: Max Null, Sergey Belov

We define the topology atop(χ) on a complete upper semilattice χ = (M, ≤). The limit points are determined by the formula lim (X) = sup{a ∈ M | {x ∈ X| a ≤ x} ∈ D}, D where X ⊆ M is an arbitrary set, D is an arbitrary non-principal ultrafilter on X. We investigate lim (X) and topology atop(χ) properties. In particular, D we prove the compactness of the topology atop(χ).
