RT Journal Article T1 Nontrivial Solutions of Non-Autonomous Dirichlet Fractional Discrete Problems A1 Cabada Fernández, Alberto A1 Dimitrov, Nikolay K1 Discrete fractional calculus K1 Green’s function K1 Existence of solutions K1 Two-point boundary value problem AB In this paper, we introduce a two-point boundary value problem for a finite fractional difference equation with a perturbation term. By applying spectral theory, an associated Green’s function is constructed as a series of functions and some of its properties are obtained. Under suitable conditions on the nonlinear part of the equation, some existence and uniqueness results are deduced.
