چکیده

Monotonicity analysis of delta fractional sums and differences order υ∈(0,1] on the time scale hZ are presented in this study. For analysis, two models discrete calculus, Riemann–Liouville Caputo, considered. There is a relationship between h-difference Caputo h-differences, which we find Therefore, after solve one, can apply same method to other one due their correlation. We show that y(z) υ-increasing Ma+υh,h, where υ function starting at a+υh greater or equal zero, then, −1Γ(1−υ)(z−(a+υh))h(−υ)y(a+υh) for each z∈Ma+h,h. Conversely, if y(a+υh) zero increasing consequently, Ma,h. Furthermore, consider some related results strictly increasing, decreasing, decreasing cases. Finally, forward difference initial value problems solutions investigated test mean theorem utilizing monotonicity results.

A monotonicity result for discrete fractional difference operators

In this note we demonstrate that if y(t) ≥ 0, for each t in the domain of t → y(t), and if, in addition, Δ0y(t) ≥ 0, for each t in the domain of t → Δ0y(t), with 1 < ν < 2, then it holds that y is an increasing function of t. This demonstrates that, in some sense, the positivity of the νth order fractional difference has a strong connection to the monotonicity of y. Furthermore, we provide a du...

On q–fractional derivatives of Riemann–Liouville and Caputo type

Abstract. Based on the fractional q–integral with the parametric lower limit of integration, we define fractional q–derivative of Riemann–Liouville and Caputo type. The properties are studied separately as well as relations between them. Also, we discuss properties of compositions of these operators. Mathematics Subject Classification: 33D60, 26A33 .
