Unique iterative solution for high-order nonlinear fractional q-difference equation based on $\psi -(h,r)$-concave operators
Abstract An objective of this paper is to investigate the boundary value problem of a high-order nonlinear fractional q-difference equation. It was to obtain a unique iterative solution for this problem by means of applying a novel fixed-point theorem of $\psi -(h,r)$-concave operator, in which the...
