 Volume 10, Number 1, 2020, Pages 153-164 Existence and uniqueness of positive solution for nonlinear fractional q-difference equation with integral boundary conditions Caixia Guo,Jianmin Guo,Shugui Kang,Huapeng Li Keywords:Fractional q-difference, integral boundary value problem, fixed point theorem, positive solution. Abstract: This paper studies a class of nonlinear fractional $q$-difference equations with integral boundary conditions. By exploiting the properties of Green""s function and two fixed point theorems for a sum operator, the existence and uniqueness of positive solutions for the boundary value problem are established. Iterative schemes for approximating the solutions are also obtained. Explicit examples are given to illustrate main results. PDF      Download reader
