A Coupled System of p-Laplacian Langevin Equations with ψ-Hilfer Fractional Derivatives and Lebesgue–Stieltjes Integral Boundary Conditions in Weighted Banach Spaces
We study a nonlinear system of two Langevin differential equations, each governed by ψ-Hilfer fractional derivatives acting through a p-Laplacian and coupled to one another both through the nonlinearities and through the boundary data. The latter consist of antiperiodic relations connecting an interior node η∈(a,b) wit...
