Semi-reflexive spaceIn the area of mathematics known as functional analysis, a semi-reflexive space is a locally convex topological vector space (TVS) X such that the canonical evaluation map from X into its bidual (which is the strong dual of the strong dual of X) is bijective. If this map is also an isomorphism of TVSs then it is called reflexive. Semi-reflexive spaces play an important role in the general theory of locally convex TVSs. Since a normable TVS is semi-reflexive if and only if it is reflexive, the concept of semi-reflexivity is primarily used with TVSs that are not normable.
Metrizable topological vector spaceIn functional analysis and related areas of mathematics, a metrizable (resp. pseudometrizable) topological vector space (TVS) is a TVS whose topology is induced by a metric (resp. pseudometric). An LM-space is an inductive limit of a sequence of locally convex metrizable TVS.
Spaces of test functions and distributionsIn mathematical analysis, the spaces of test functions and distributions are topological vector spaces (TVSs) that are used in the definition and application of distributions. Test functions are usually infinitely differentiable complex-valued (or sometimes real-valued) functions on a non-empty open subset that have compact support. The space of all test functions, denoted by is endowed with a certain topology, called the , that makes into a complete Hausdorff locally convex TVS.
Espace de MontelEn topologie des espaces vectoriels, on appelle espace de Montel un espace vectoriel topologique localement convexe séparé, tonnelé et dont tout fermé borné est compact. Le nom provient du mathématicien Paul Montel. Tout espace de Montel est réflexif et quasi complet. Son dual fort est un espace de Montel. Le quotient d'un espace de Fréchet-Montel par un sous-espace fermé peut n'être pas réflexif, et a fortiori ne pas être un espace de Montel (en revanche, le quotient d'un espace de Fréchet-Schwartz par un sous-espace fermé est un espace de Fréchet-Montel).
