Weba Banach space is reflexive if its unit ball is uniformly non-square, and also that there is a large class of spaces that are reflexive but are not isomorphic to a space whose unit ball is uniformly non-square. It is conjectured that a Banach space is reflexive if its subspaces are uniformly non-'1' for some n (see Defi-nition 2.1). If a Banach space is isomorphic to a reflexive Banach space then is reflexive. Every closed linear subspace of a reflexive space is reflexive. The continuous dual of a reflexive space is reflexive. Every quotient of a reflexive space by a closed subspace is reflexive.

WebIn mathematics, the bounded inverse theorem (or inverse mapping theorem) is a result in the theory of bounded linear operators on Banach spaces.It states that a bijective bounded linear operator T from one Banach space to another has bounded inverse T −1.It is equivalent to both the open mapping theorem and the closed graph theorem. WebMar 18, 1977 · reflexive space, then EK is a dual space. Special case 2. If Ε = V and K = S° where S is a convex balanced neighborhood of 0 in V, then EK is a dual space. (S° denoting the polar set in E.) 2. Examples. We shall give some more or less well-known applications of our criterion. a) Let M,d be a metric space and let Λ (Μ) be the Banach space ... http://staff.ustc.edu.cn/~wangzuoq/Courses/15F-FA/Notes/FA18.pdf artikel tentang loyal pns
