Solutions to Variable-Order Fractional BVPs with Multipoint Data in <i>W</i><sup>s,p</sup> Spaces

This study explores the existence of positive solutions within a Sobolev space for a boundary value problem that involves Riemann–Liouville fractional derivatives of variable order. The analysis utilizes the method of upper and lower solutions in combination with the Schauder fixed-point theorem. To...
