WebB(H) into the algebra of bounded operators on a Hilbert space H. Thus Banach spaces are given a structure resembling that of a C∗algebra, but contrary to C∗algebras which admit a privileged realization, Banach spaces may admit many inequivalent operator space structures. We give a very brief outline of that theory in § 13. Lebesgue spaces are function spaces associated to measure spaces (X, M, μ), where X is a set, M is a σ-algebra of subsets of X, and μ is a countably additive measure on M. Let L (X, μ) be the space of those complex-valued measurable functions on X for which the Lebesgue integral of the square of the absolute value of the function is finite, i.e., for a function f in L (X, μ), The inner product of functions f and g in L (X, μ) is then defined as

WebFeb 18, 2016 · $\begingroup$ Characterizing Hilbert spaces isomorphically is a very interesting topic in Banach space theory. Another one is that every nuclear operator on the space has absolutely summable eigenvalues. Open is whether a Banach space all of whose subspaces have an unconditional basis must be isomorphic to a Hilbert space. WebIn the case of one Hilbert space H, the space L(H,H) is simply denoted by B(H). Given T∈ B(H 1,H 2) and S∈ B(H 2,H 3), their composition S T∈ B(H 1,H 3) will be simply denoted by ST. We know that B(H) is a unital Banach algebra. This Banach algebra will be our main tool used for investigating bounded operators. The general theme of

WebA Hilbert space is a complete, inner product space. Every Hilbert space is a Banach space but the reverse is not true in general. In a Hilbert space, we write f n!f to mean that jjf n fjj!0 as n!1. Note that jjf n fjj!0 does NOT imply that f n(x) !f(x). For this to be true, we need the space to be a reproducing kernel Hilbert space which we ...
