摘要
We establish some properties of the bilateral Riemann-Liouville fractional derivative D-s. We set the notation, and study the associated Sobolev spaces of fractional order s, denoted by W-s,W-1(a,b), and the fractional bounded variation spaces of fractional order s, denoted by BVs(a,b). Examples, embeddings and compactness properties related to these spaces are addressed, aiming to set a functional framework suitable for fractional variational models for image analysis.
