We establish some notation and properties of the bilateral Riemann-Liouville fractional derivative D-s. We introduce the associated Sobolev spaces of fractional order s, denoted by W-s,W-1(a, b), and the Bounded Variation spaces of fractional order s, denoted by BVs(a, b): these spaces are studied with the aim of providing a suitable functional framework for fractional variational models in image analysis.

Abstract
We establish some notation and properties of the bilateral Riemann-Liouville fractional derivative D-s. We introduce the associated Sobolev spaces of fractional order s, denoted by W-s,W-1(a, b), and the Bounded Variation spaces of fractional order s, denoted by BVs(a, b): these spaces are studied with the aim of providing a suitable functional framework for fractional variational models in image analysis.File in questo prodotto:
