Special Issue Information
Dear Colleagues,
Fractional-order differential equations have attracted great interest for their use in modeling diverse dynamical systems in different fields, including physics, engineering, and biology. In fractional-order models, the order of the derivatives acts as a degree of freedom and can increase the accuracy of modeling. Therefore, the fractional-order models can describe the natural systems more precisely than the integer-order models. Furthermore, fractional calculus considers the memory effect, a significant factor in many processes, such as biological and financial systems. These motivations have led to substantial advances in fractional-order systems; however, many challenging problems still exist. This Special Issue deals with the unresolved problems and new advancements of fractional-order systems.
One of the hottest topics in the nonlinear dynamics field is studying the networks of coupled oscillators. The interactions among the systems in a network lead to the development of collective behaviors such as synchronization, chimera states, spiral waves, coherence resonance, etc. The emergence of these phenomena in a network relies on several factors, including the dynamics of the oscillators and the configuration of the network. Therefore, using fractional-order derivatives in the describing equations of the network can influence its collective dynamics and alter its behavior. Despite the numerous studies focusing on the behavior of a network of integer-order oscillators, less attention has been paid to the coupled fractional-order systems. Consequently, one of this Special Issue's aims is to focus on the networks of fractional-order systems.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
