A locally convex space for which all continuous linear mappings into an arbitrary Banach space are nuclear operators (cf. Nuclear operator). The concept of a nuclear space arose in an investigation of the question: For what spaces are the analogues of Schwartz' kernel theorem valid (see Nuclear bilinear form)? The fundamental results in the theory of nuclear spaces are due to A. Grothendieck. The function spaces . note that they are not equivalent for sequences or functions! In particular, a sequence of functions may converge in L1 but not in L∞ or vice-versa.) Banach Spaces When the induced metric is complete, the normed vector space is called a Banach space. So, a closed linear subspace of a Banach space is itself a Banach space. 3.

Introduction to Banach Spaces 1. Uniform and Absolute Convergence As a preparation we begin by reviewing some familiar properties of Cauchy sequences and uniform limits in the setting of metric spaces. Definition A metric space is a pair (X;ˆ), where Xis a set and ˆis a real-valued function on X Xwhich satis es that, for any x, y, z2X. Non-Banach limits Ck(R), C1(R) of Banach spaces Ck[a;b] For a non-compact topological space such as R, the space C o (R) of continuous functions is not a Banach space with sup norm, because the sup of the absolute value of a continuous function may be +1.

2. Banach spaces Deﬁnitions and examples We start by deﬁning what a Banach space is: Deﬁnition A Banach space is a complete, normed, vector space. Comment Completeness is a metric space concept. In a normed space the metric is d(x,y)=￿x−y￿. Note that this metric satisﬁes the following “special" properties. § A Topological Convergence in the Space of Operators § Functional on the Space ℱ0 § A Characterization of Operator Convergence Type I' § Metrizable Topological Vector Spaces § The Space ℱ0 as a Metric Space § The Space of Operators as the Union of Metric Spaces § Bounded Sets in the Space of Operators §

A complete normed space is called a Banach space. While there is seemingly no prototypical example of a Banach space, we still give one example of a Banach space: (), the space of all continuous functions on a compact space, can be identified with a Banach space.

Banach Spaces Many linear equations may be formulated in terms of a suitable linear operator acting on a Banach space.

In this chapter, we study Banach spaces and linear oper-ators acting on Banach spaces in greater detail. We give the de nition of a Banach space and illustrate it with a number of examples. We show that a linear operator.

Let E,F be Banach spaces where F = E' or vice versa. If F has the approximation property, then the space of nuclearly entire functions of bounded type, $ℋ_{Nb}(E)$, and the space of exponential type functions, Exp(F), form a dual pair.
