		Although such spaces are not necessarily normable they have, as with semi normed spaces, a convex local basis for 0.
		Fréchet spaces are locally convex spaces which are metrisable and complete with respect to this metric.
		In particular it is not locally convex, and its dual space is 0.

		The elements of topological vector spaces are typically functions, and the topology is often defined so as to capture a particular notion of convergence of sequences of functions.
		Fréchet spaces: these are complete locally convex spaces where the topology comes from a translation-invariant metric, or equivalently: from a countable family of semi-norms.
		A vector space is an abelian group with respect to the operation of addition, and in a topological vector space the inverse operation is always continuous (since it is the same as multiplication by -1).

	Locally convex (Site not responding. Last check: 2007-10-21)
		In functional analysis, a topological vector space is called locallyconvex if its topology is defined by a set of convex neighborhoods of 0.Every normed space is locally convex, since the triangle inequality ensures that all balls are convex.
		More formally, a locally convex topological vector space (or Locally convex space) is a topological vector space with the followinglocal convexity condition: there exists a base of neighbourhoods of 0 consisting of convex sets.Equivalently, the topology is that defined by a family of semi-norms.
		Every Banach space is a locally convex space, and much of the theory oflocally convex spaces generalises parts of the theory of Banach spaces.

	Locally convex topological vector space - Encyclopedia, History, Geography and Biography
		Conversely for every non-empty family of subsets $\mathcal{B}$ of a vector space $X$ with the above properties, there exists exactly one topology $\tau$ so that $(X,\tau)$ is a locally convex topological vector space and $\mathcal{B}$ a locally convex basis.
		spaces with $p \ge 1$ are locally convex.
		A family of seminorms $P$ can be used to define a locally convex basis $\mathcal{B}$ for a vector space over a field $\mathbb{F}$ and thus a unique locally convex topology.

		A partial -algebra is a vector* space $\A$, equipped with a multiplication $(x,y) \mapsto x \cdot y \in \A$ which is defined only for some pairs $x,y\in \A$ (in which case $y$ is called a right multiplier of $x$).
		Then $\A$ is called a {\em topological partial *-algebra } if it satisfies a number of conditions, which all amount to require that the topology $\tau$ fits with the multiplier structure of $\A$.
		Vector fields play a very important role in the classical differential geometry on manifolds and can be defined in purely algebraic way.

		Kühn and Rösler (1998) showed that although convexity and compactness conclusions of Lyapunov's theorem may fail for measures defined on different sigma-algebras of the same set, they do hold if the sigma-algebras are nested, which is exactly the setting of classical optimal stopping theory.
		Maritz (1980-81) showed that the bilinear integral of a set-valued function with values in an arbitrary Banach space is convex, provided the integral is a subset of a finite dimensional space and the measure is atomless.
		If mu is an atomless finite-dimensional vector measure (not necessary finite), then the range of mu is convex, the closure of the range does not contain a line and each compact extreme face of the closure of the range is contained in the range.

		This notion of "continuous linear functional on the space of test functions" is therefore used as the definition of a distribution.
		The dual space of the topological vector space D(U), consisting of all continuous linear functionals S : D(U) → R, is the space of all distributions on U; it is a vector space and is denoted by D'(U).
		These functions form a complete topological vector space with a suitably defined family of seminorms.

		In mathematics, the weak topology on a set, with respect to a collection of functions from that set into topological spaces, is the weakest (that is, smallest) topology on the set which makes all the functions continuous.
		A particularly important example of a weak topology is that on a normed vector space with respect to its (continuous) dual.
		The weak topology on X is the weakest topology (the topology with the least open sets) such that all elements of X ' remain continuous.
