Banach Disk
In functional analysis, two methods of constructing Normed vector space, normed spaces from Absolutely convex set, disks were systematically employed by Alexander Grothendieck to define nuclear operators and nuclear spaces. One method is used if the disk D is bounded: in this case, the auxiliary normed space is \operatorname D with norm p_D(x) := \inf_ r. The other method is used if the disk D is absorbing set, absorbing: in this case, the auxiliary normed space is the Quotient space (linear algebra), quotient space X / p_D^(0). If the disk is both bounded and absorbing then the two auxiliary normed spaces are canonically isomorphic (as topological vector spaces and as normed spaces). Preliminaries A subset of a vector space is called a Absolutely convex set, disk and is said to be disked, Absolutely convex set, absolutely convex, or convex balanced if it is Convex set, convex and balanced set, balanced. If C and D are subsets of a vector space X then D Absorbing set, absorb ... [...More Info...] [...Related Items...]

Injective Tensor Product
In mathematics, the injective tensor product of two topological vector spaces (TVSs) was introduced by Alexander Grothendieck and was used by him to define nuclear spaces. An injective tensor product is in general not necessarily Complete topological vector space, complete, so its completion is called the . Injective tensor products have applications outside of nuclear spaces. In particular, as described below, up to TVSisomorphism, many TVSs that are defined for real or complex valued functions, for instance, the Schwartz space or the space of continuously differentiable functions, can be immediately extended to functions valued in a Hausdorff Locally convex topological vector space, locally convex TVS with any need to extend definitions (such as "differentiable at a point") from real/complexvalued functions to valued functions. Preliminaries and notation Throughout let ''X'', ''Y'', and ''Z'' be topological vector spaces and L : X \to Y be a linear map. * L : X \to Y is a t ... [...More Info...] [...Related Items...]

DFspace
In the field of functional analysis, DFspaces, also written (''DF'')spaces are locally convex topological vector space having a property that is shared by locally convex metrizable topological vector spaces. They play a considerable part in the theory of topological tensor products. DFspaces were first defined by Alexander Grothendieck and studied in detail by him in . Grothendieck was led to introduce these spaces by the following property of strong duals of metrizable spaces: If X is a Metrizable topological vector space, metrizable locally convex space and V_1, V_2, \ldots is a sequence of convex 0neighborhoods in X^_b such that V := \cap_ V_i absorbs every strongly bounded set, then V is a 0neighborhood in X^_b (where X^_b is the continuous dual space of X endowed with the strong dual topology). Definition A locally convex topological vector space (TVS) X is a DFspace, also written (''DF'')space, if # X is a countably quasibarrelled space (i.e. every strongly bou ...

Fréchet Space
In functional analysis and related areas of mathematics, Fréchet spaces, named after Maurice Fréchet, are special topological vector spaces. They are generalizations of Banach spaces (normed vector spaces that are Complete space, complete with respect to the Metric (mathematics), metric induced by the Norm (mathematics), norm). All Banach space, Banach and Hilbert spaces are Fréchet spaces. Spaces of infinitely differentiable Function (mathematics), functions are typical examples of Fréchet spaces, many of which are typically Banach spaces. A Fréchet space X is defined to be a Locally convex topological vector space, locally convex Metrizable topological vector space, metrizable topological vector space (TVS) that is Complete topological vector space, complete as a TVS, meaning that every Cauchy sequence in X converges to some point in X (see footnote for more details).Here "Cauchy" means Cauchy with respect to the Complete topological vector space, canonical uniformity ...

Null Sequence
As the positive integer n becomes larger and larger, the value n\cdot \sin\left(\tfrac1\right) becomes arbitrarily close to 1. We say that "the limit of the sequence n\cdot \sin\left(\tfrac1\right) equals 1." In mathematics, the limit of a sequence is the value that the terms of a sequence "tend to", and is often denoted using the \lim symbol (e.g., \lim_a_n).Courant (1961), p. 29. If such a limit exists, the sequence is called convergent. A sequence that does not converge is said to be divergent. The limit of a sequence is said to be the fundamental notion on which the whole of mathematical analysis ultimately rests. Limits can be defined in any metric space, metric or topological space, but are usually first encountered in the real numbers. History The Greek philosopher Zeno of Elea is famous for formulating Zeno's paradoxes, paradoxes that involve limiting processes.

Alexander Grothendieck
Alexander Grothendieck (; ; ; 28 March 1928 – 13 November 2014) was a mathematician who became the leading figure in the creation of modern algebraic geometry. His research extended the scope of the field and added elements of commutative algebra, homological algebra, sheaf theory and category theory to its foundations, while his socalled Grothendieck's relative point of view, "relative" perspective led to revolutionary advances in many areas of pure mathematics. He is considered by many to be the greatest mathematician of the 20th century. Born in Germany, Grothendieck was raised and lived primarily in France, and he and his family were persecuted by the Nazi Germany, Nazi regime. For much of his working life, however, he was, in effect, Statelessness, stateless. As he consistently spelled his first name "Alexander" rather than "Alexandre" and his surname, taken from his mother, was the Dutchlike Low German "Grothendieck", he was sometimes mistakenly believed to be of D ...
