Proof of Riesz representation theorem 2. We shall deduce the result from the spe- cial case of the Cantor set, using Hahn-Banach theorem on extension of linear functionals (see Thm 5.6 in Folland). Let Λ∈ C(X) ∗ be a positive functional. Let ...
In this paper we develop a generalization of Riesz representationtheorem on generalized n-inner product spaces. We show that any alternatingn-linear functional on a finitely generated standard generalizedn-inner product space can be represented by a finite number ofn-tuples of vectors. The proof ...
摘要: This paper main objective is to present the Riesz Representation Theorem and to collect some consequences of it for the separation problem in Hilbert spaces. Another theorem, important to the sequence of the paper, will also be presented and demonstrated. 被引量: 8 年份: 2011 收藏...
THEOREM 1.5 (Josefson-Nissenzweig) If X is an infinite dimensional Banach space, then there exists a sequence (x*n) in X* of norm-one functionals that go to 0 in the weak* topology. OUTLINE OF THE PROOF Nissenzweig used an observation of A. Pelczyński to construct a measure-theoretic...

. by the discussion at the beginning of the proof, we have a continuous representation of g on the fréchet space \(\mathcal {s}(g)\) , where g acts by left translations, and moreover all elements of \(\mathcal {s}(g)\) are smooth vectors for this representation, as \(\math...
