Abstract

In this paper, we investigate the existence and uniqueness solutions of nonlinear boundary value problems for system of Caputo type nonlinear fractional differential equations of the form:
\begin{equation*}\label{*}
\left\{
\begin{array}{c}
 ^cD_{a^{+}}^{q;\psi} u_{i}(t)=F_{i}(t,u_{1}(t),u_{2}(t)) \quad t\in J=[a,b],\\
 \phi(v_{i}(a),v_{i}(b))=0.
          \end{array}
        \right.  \end{equation*}\\
To develop a monotone iterative technique by introducing upper and lower solutions to Caputo type fractional differential equations  with nonlinear boundary conditions. The monotone method yield monotone sequences which converges to uniformly and monotonically to extremal solutions.
