Relative Chaos for -Semigroups Beyond Topological Notions
El-Mehdi Nafia, Aziz El Ghazouani, M'hamed El Omari
We investigate instability phenomena for linear evolution equations within the framework of --semigroups on infinite--dimensional spaces. We show that Devaney chaos, being for…

Time Reparametrization and Chaotic Dynamics in Conformable -Semigroups
Mohamed Khoulane, Aziz El Ghazouani, M'hamed El Omari
Conformable derivatives provide a fractional-looking calculus that remains local and admits a simple representation through classical derivatives with explicit weights. In this pap…

Time Reparametrization, Not Fractional Calculus: A Reassessment of the Conformable Derivative
Aziz El Ghazouani, Fouad Ibrahim Abdou Amir, Khoulane Mohamed +1
The conformable derivative has been promoted in numerous publications as a new fractional derivative operator. This article provides a critical reassessment of this claim. We demon…
