Monotonicity and convexity for nabla fractional \((q,h)\)-differences. (English) Zbl 1364.39009
The authors study the monotonicity and convexity of the nabla fractional \((q,h)\)-difference operator. Furthermore, they show that if the \(\alpha\)th-order nabla fractional \((q,h)\)-difference is positive, then the \(N\)th-order nabla fractional \((q,h)\)-difference is positive, where \(N-1<\alpha\leq N\), \(N=1,2\), that is the \(\alpha\)th-order nabla fractional \((q,h)\)-difference has a strong connection to the monotonicity and convexity.
