Special Issue Information
Dear Colleagues,
Complex systems consist of a large number of interconnected elements that interact with each other in an adaptive and emergent way. These systems occur in diverse fields, including physics, biology, economics, sociology and computer science. For instance, the main characteristic of a complex system is that its overall properties cannot simply be deduced from the behavior of the individual components, but result from their interactions.
Some key characteristics of complex systems are listed below:
- Nonlinear interactions;
- Emergent behavior;
- Sensitivity to initial conditions;
- Self-organization;
- Adaptive dynamics.
In such a context, nonlinear dynamics studies systems in which changes are not proportional to the applied forces, and where interactions can produce unforeseen effects. Many complex systems are governed by nonlinear dynamics, which explains phenomena such as the following:
- Deterministic Chaos—some complex systems, although governed by deterministic equations, exhibit seemingly random behavior due to sensitivity to initial conditions.
- Strange attractors—in nonlinear dynamics, a system may have a set of states towards which it naturally tends, but its trajectory is highly complex and unpredictable. This phenomenon explains why some complex systems do not stabilize in a fixed equilibrium, but oscillate in a complicated way.
- Bifurcations—sudden changes in the behavior of a system when a particular variable crosses a critical threshold.
Taking the above into account, this Special Issue aims at the correspondence between properties of complex systems and nonlinear dynamics. Both theoretical and experimental approaches are considered.

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.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
