Abstract
In this paper, we deal with the existence of a non-trivial solution for the following
fractional discrete boundary-value problem for any k 2 [1; T ]N0
{
T +1∇α
k (k ∇α
0 (u(k))) + k ∇α
0 (T +1∇α
k (u(k))) + ϕp(u(k)) = f (k; u(k));
u(0) = u(T + 1) = 0;
where 0 < < 1 and k ∇α
0 is the left nabla discrete fractional difference and T +1∇α
k is the right nabla discrete fractional difference f : [1; T ]N0  R ! R is a continuous function,  > 0
is a parameter and ϕp is the so called p-Laplacian operator defined as ϕp(s) = jsjp−2s and
1 < p < +1. The technical method is variational approach for differentiable functionals.
Several examples are included to illustrate the main results.
