Boundary value problem with fractional p-Laplacian operator

The aim of this paper is to obtain the existence of solution for the fractional p-Laplacian Dirichlet problem with mixed derivatives \begin{eqnarray*} &{{t}}D{T}^{\alpha}\left(|{0}D{t}^{\alpha}u(t))|^{p-2}{{0}}D{t}^{\alpha}u(t)\right) = f(t,u(t)), ;t\in [0,T],\ &u(0) = u(T) = 0, \end{eqnarray*} where $\frac{1}{p}<\alpha <1$, $1<p<\mathrm{\infty }$ and $f:[0,T]\times $\mathbb{R}$ \to $\mathbb{R}$$ is a Carath'eodory function wich satisfies some growth conditions. We obtain the existence of nontrivial solution by using the Mountain Pass Theorem.
