Boundedness of the Weyl fractional integral on one-sided weighted Lebesgue and Lipschitz spaces

Descrição
Resumo:In this paper we introduce the one-sided weighted spaces L-w (β), -1 <β< 1. The purpose of this definition is to obtain an extension of the Weyl fractional integral operator I+α from Lp w into a suitable weighted space. Under certain condition on the weight w, we have that L-w (0) coincides with the dual of the Hardy space H1 -(w). We prove for 0 <β< 1, that L- w (β) consists of all functions satisfying a weighted Lipschitz condition. In order to give another characterization of L- w (β), 0 ≤ β < 1, we also prove a one-sided version of John-Nirenberg Inequality. Finally, we obtain necessary and sufficient conditions on the weight w for the boundedness of an extension of I+ α from Lp w into L- w (β), -1 <β< 1, and its extension to a bounded operator from L- w (0) into L- w (α).
