Web) (Theorem 1 of Lecture 26). We are interested in characterizing the dual space of Lp(X; ) for 1 p <1and a ˙-finite measure. This is given by the Riesz Representation Theorem that says that Lp(X; ) ˘= Lq(X; ) where 1 q + 1 q = 1. First recall the following Proposition (1) Let 1 p <1, q the conjugate of p, E a -measurable set and g 2Lq(E ... WebNOTES ON THE RIESZ REPRESENTATION THEOREM 5 Demonstra˘c~ao. If fis in Lp(X;A; ) then the set f 1 IRnf0g is ˙- nite for and thus, by item (b) of Lemma 2.4, and bf coincide on all measurable subsets of f 1 IRnf0g. This proves that: Z X jfjpd = Z X jfjpd bf; i.e., (2.2) is an isometric immersion. In order to prove that (2.2) is surjective

WebUsing Riesz original notation it looked like this: A[f(x)] = 1 0 f(x)d (x); where is a function of bounded variation on the unit interval. This has become known as the Riesz representation theorem. Since Riesz’s originial proof, mathematicians have been able to extend this theorem to concern more general spaces, and thus they have created a
