WebTheorem 2.1 (The Riesz Representation Theorem). Let Hbe a Hilbert space and let : H!C (or R) be a bounded linear functional on H. Then, there is a unique g2Hsuch that, for all f2H, ( f) = hf;gi. Proof. The functional is a bounded operator that maps Hinto the scalars. It follows from our discussion of bounded operators that the null space of The Riesz representation theorem states that this map is surjective (and thus bijective) when is complete and that its inverse is the bijective isometric antilinear isomorphism Consequently, every continuous linear functional on the Hilbert space can be written uniquely in the form [1] where for every The … See more This article describes a theorem concerning the dual of a Hilbert space.

WebThe Riesz representation theorem (henceforth called the Riesz theorem) classi es the bounded linear functionals on the space C[a;b], of continuous functions on the closed, bounded interval [a;b]. A linear functional on C[a;b] is a linear transforma-tion L: C[a;b] !R, and it therefore satis es the following two properties.
