Positive solutions for a system of nonlinear semipositone fractional \(q\)-difference equations with \(q\)-integral boundary conditions

In this paper, by virtue of fixed point index on cones, we obtain
two existence theorems of positive solutions for a system of
nonlinear semipositone fractional \(q\)-difference equations with
\(q\)-integral boundary conditions. Concave functions and nonnegative matrices are used to characterize the
coupling behavior of our nonlinearities.
