Specialty Definition: Reflexive space

(From Wikipedia, the free Encyclopedia)

In functional analysis, a Banach space is called reflexive if it satisfies a certain abstract property involving dual spaces. Reflexive spaces turn out to have desirable geometric properties.

Definition

Suppose X is a Banach space. We denote by X' its continuous dual, i.e. the space of all continuous linear maps from X to the base field (R or C). This is again a Banach space, as explained in the dual space article. So we can form the double dual X", the continuous dual of X'. There is a natural continuous linear transformation

J : XX"
defined by
J(x)(φ) = φ(x)     for every x in X and φ in X'.
As a consequence of the Hahn-Banach theorem, J is norm-preserving (i.e., ||J(x)||=||x|| ) and hence injective. The space X is called reflexive if J is bijective.

Examples

All Hilbert spaces are reflexive, as are the Lp spaces for 1 < p < ∞. More generally: all uniformly convex Banach spaces are reflexive.

Properties

Every closed subspace of a reflexive space is reflexive.

The promised geometric property of reflexive spaces is the following: if C is a closed non-empty convex subset of the reflexive space X, then for every x in X there exists a c in C such that ||x - c|| minimizes the distance between x and points of C. (Note that while the minimial distance between x and C is uniquely defined by x, the point c is not.)

A space is reflexive if and only if its dual is reflexive.

A space is reflexive if and only if its unit ball is compact in the weak topology.
