Asymmetric locally convex spaces
The aim of the present paper is to introduce the asymmetric locally convex spaces and to prove some basic properties. Among these I do mention the analogs of the EidelheitTuckey separation theorems, of the Alaoglu-Bourbaki theorem on the weak compactness of the polar of a neighborhood of 0, and a Krein-Milman-type theorem. These results extend those obtained by Garcı́a-Raffi et al. (2003) and Co...
متن کاملSeminorms and Locally Convex Spaces
The first point is to describe vector spaces with topologies arising from (separating) families of semi-norms. These all turn out to be locally convex, for straightforward reasons. The second point is to check that any locally convex topological vectorspace's topology can be given by a collection of seminorms. These seminorms are made in a natural way from a local basis consisting of balanced c...

متن کاملSmooth Locally Convex Spaces * 1 )
The main theorem is Let E be a separable (real) Frèchet space with a nonseparable strong dual Then E is not strongly Dp-smooth. It follows that if X is uncountable, locally compact, a-compact, metric space, then C(X) (with the topology of compact convergence) does not have a class of seminorms which generate its topology and are Frechet differentiable (away from their null-spaces). 1. Prelimina...
متن کاملCharacterizations of $L$-convex spaces
In this paper, the concepts of $L$-concave structures, concave $L$-interior operators and concave $L$-neighborhood systems are introduced. It is shown that the category of $L$-concave spaces and the category of concave $L$-interior spaces are isomorphic, and they are both isomorphic to the category of concave $L$-neighborhood systems whenever $L$ is a completely distributive lattice. Also, it i...
