The existence of nonnegative solutions for a nonlinear fractional q-differential problem via a different numerical approach.

This paper deals with the existence of nonnegative solutions for a class of boundary value problems of fractional q-differential equation ${}^{c}D_{q}^{σ} [k] (t) = w (t, k (t),^{c} D_{q}^{ζ} [k] (t))$ with three-point conditions for $t \in (0, 1)$ on a time scale $T_{t_{0}} = {t : t = t_{0} q^{n}} \cup {0}$ , where $n \in N$ , $t_{0} \in R$ , and $0 < q < 1$ , based on the Leray-Schauder nonlinear alternative and Guo-Krasnoselskii theorem. Moreover, we discuss the existence of nonnegative solutions. Examples involving algorithms and illustrated graphs are presented to demonstrate the validity of our theoretical findings.

期刊介绍： The aim of this journal is to provide a multi-disciplinary forum of discussion in mathematics and its applications in which the essentiality of inequalities is highlighted. This Journal accepts high quality articles containing original research results and survey articles of exceptional merit. Subject matters should be strongly related to inequalities, such as, but not restricted to, the following: inequalities in analysis, inequalities in approximation theory, inequalities in combinatorics, inequalities in economics, inequalities in geometry, inequalities in mechanics, inequalities in optimization, inequalities in stochastic analysis and applications.
