“…Since [p] is a closed left ideal of G LU C for every p ∈ ϕ, we always have |π(ϕ)| ≤ 2 2 κ (see, for example, [14]). Recall that U(G) = ϕ κ is an ideal of G LU C (see [2]). Therefore, the assumption ϕ κ ⊆ ϕ in the next theorem implies ϕ ⊆ ϕ κ = U(G).…”

“…All semigroup compactifications of a semitopological semigroup as a collection of z-ultrafilters or e-ultrafilters have been described, see [1], [2], [3] and [4] for more details and some applications. This approach gives us a new light on studying this kind of compactifications.…”

“…This approach gives us a new light on studying this kind of compactifications. It seems that the methods presented in [1], [2], [3] and [4] can serve as a valuable tool in the study of semigroup compactifications and also of topological compactifications. But this methods depend on concepts of topology on semigroups.…”
