On a Theorem by Lions and Peetre about Interpolation between a Banach Space and Its Dual

چکیده
We show that if the duality between a Banach space A and its anti-dual A* is given by the inner product of a Hilbert space H, then (A, A*)1/2,2 = H = (A,A*)[l,2~, provided A satisfies certain mild conditions. We do not assume A is reflexive. Applications are given to normed ideals of operators.

Lecture Notes on Duality and Interpolation Spaces
Known or essentially known results about duals of interpolation spaces are presented, taking a point of view sometimes slightly different from the usual one. Particular emphasis is placed on Alberto Calderón’s theorem describing the duals of complex interpolation spaces. The pace is slow, since these notes are intended for graduate students who have just begun to study interpolation spaces. Thi...
متن کاملSimultaneous Approximation in Scales of Banach Spaces
The problem of verifying optimal approximation simultaneously in different norms in a Banach scale is reduced to verification of optimal approximation in the highest order norm. The basic tool used is the Banach space interpolation method developed by Lions and Peetre. Applications are given to several problems arising in the theory of finite element methods.
متن کاملThe Quasinormed Neumann–schatten Ideals and Embedding Theorems for the Generalized Lions–peetre Spaces of Means
For the spaces φ(X0, X1)p0,p1 , which generalize the spaces of means introduced by Lions and Peetre to the case of functional parameters, necessary and sufficient conditions are found for embedding when all parameters (the function φ and the numbers 1 ≤ p0, p1 ≤ ∞) vary. The proof involves a description of generalized Lions–Peetre spaces in terms of orbits and co-orbits of von Neumann–Schatten ...
متن کاملAn ordinal version of some applications of the classical interpolation theorem
Let E be a Banach space with a separable dual. Zippin’s theorem asserts that E embeds in a Banach space E1 with a shrinking basis, and W. J. Davis, T. Figiel, W. B. Johnson and A. Pełczyński have shown that E is a quotient of a Banach space E2 with a shrinking basis. These two results use the interpolation theorem established by W. J. Davis, T. Figiel, W. B. Johnson and A. Pełczyński. Here, we ...
متن کاملL p-SPACES FOR 0 < p < 1
In a first course in functional analysis, a great deal of time is spent with Banach spaces, especially the interaction between such spaces and their dual spaces. Banach spaces are a special type of topological vector space, and there are important topological vector spaces which do not lie in the Banach category, such as the Schwartz spaces. The most fundamental theorem about Banach spaces is t...
