Abstract:

This paper investigates the existence of unique positive solution for a class of fractional boundary value problems involving the $p$-Laplacian operator, a fractional derivative term in the nonlinearity $f$ and nonlinear integral terms in the boundary conditions. By constructing appropriate auxiliary boundary value problems and equivalence classes on cone, and using the theory of cone and the method of sum operators, some sufficient conditions for the existence of unique positive solution are obtained, in addition, a monotone iterative sequence uniformly converging to the unique positive solution is constructed. Finally, an example is given to illustrate the main result.
