چکیده
In this paper, we study the complete ⋆-metric semigroups and groups Raǐkov completion of invariant groups. We obtain following. (1) Let (X,d⋆) be a space containing semigroup (group) G that is dense subset X. If restriction d⋆ on invariant, then X can become as subgroup, (2) (G,d⋆) group such G. Then, if only (G,τd⋆) complete.

A remark on left invariant metrics on compact Lie groups
The investigation of manifolds with non-negative sectional curvature is one of the classical fields of study in global Riemannian geometry. While there are few known obstruction for a closed manifold to admit metrics of non-negative sectional curvature, there are relatively few known examples and general construction methods of such manifolds (see [Z] for a detailed survey). In this context, it...

Let S be a locally compact foundation semigroup with identity and be its semigroup algebra. Let X be a weak*-closed left translation invariant subspace of In this paper, we prove that X is invariantly complemented in if and only if the left ideal of has a bounded approximate identity. We also prove that a foundation semigroup with identity S is left amenab...

متن کاملCDM Semigroups and Groups
ly we know that 〈A 〉 always exists since 〈A 〉 = ⋂ {H ⊆ G | A ⊆ H subgroup } But computationally this is useless: we already have to know all subgroups (containing A) to compute the intersection. Even if G is finite and relatively small, there is no hope to build an algorithm on this characterization. Also note that 〈A 〉 is one of the H’s on the right hand side (impredicative definition). So how...
