Due to this importance, in this study, a qualitative analysis of the solutions of a delayed and constant coefficient fractal differential equation with more than one fractional derivative was performed. In the equation under consideration, the derivatives are the Riemann–Liouville fractional derivatives. In the proof of the obtained results, Laplace transform formulas of the Riemann–Liouville fractional derivative and some inequalities are used. We also provide some examples to check the accuracy of our results.eninfo:eu-repo/semantics/openAccessFractional derivative, fractional-order differential equations, oscillatory behavior, qualitative analysisarticle10.3390/math121624352-s2.0-852025897061216
