Variational Formulations for Fractional Integral and Differential Equations

Delfim F. M. Torres

Given a fractional-order linear equation $L^{I^} \pm u = f$ , we define an appropriate symmetric bilinear form so that the fractional operator $L^{I^} \pm$ is symmetric with respect to that bili…

Towards a Gagliardo-Type Theory of Fractional Sobolev Spaces on Arbitrary Time Scales

Hafida Abbas, Abdelhalim Azzouz, Praveen Agarwal +1

We propose a systematic Gagliardo-type formulation of fractional Sobolev spaces on arbitrary time scales, based on the Lebesgue Delta-measure and the off-diagonal interaction domai…
