s-Topological vector spaces
In this paper, we have dened and studied a generalized form of topological vector spaces called s-topological vector spaces. s-topological vector spaces are dened by using semi-open sets and semi-continuity in the sense of Levine. Along with other results, it is proved that every s-topological vector space is generalized homogeneous space. Every open subspace of an s-topological vector space is...
متن کاملOn $beta-$topological vector spaces
We introduce and study a new class of spaces, namely $beta-$topological vector spaces via $beta-$open sets. The relationships among these spaces with some existing spaces are investigated. In addition, some important and useful characterizations of $beta-$topological vector spaces are provided.

متن کاملTopological vector spaces
Each space C N = {f ∈ C c (R) : sptf ⊂ [−N,N ]} ⊂ C[−N,N ] is strictly smaller than the space C[−N,N ] of all continuous functions on the interval [−N,N ], since functions in C N must vanish at the endpoints. Still, C o N is a closed subspace of the Banach space C [−N,N ] (with sup norm), since a sup-norm limit of functions vanishing at ±N must also vanish there. Thus, each individual C N is a ...

Theorem 1.4. Let X be a tvs and let F be a local base at 0. Then (i) U, V ∈ F ⇒ there exists W ∈ F such that W ⊆ U ∩ V . (ii) If U ∈ F , there exists V ∈ F such that V + V ⊆ U . (iii) If U ∈ F , there exists V ∈ F such that αV ⊆ U for all α ∈ K such that |α| ≤ 1. (iv) Any U ∈ J is absorbing, i.e. if x ∈ X, there exists δ > 0 such that ax ∈ U for all a such that |a| ≤ δ. Conversely, let X be a l...
