Call for Special Sessions

Special Sessions supplement the regular program of ICDEA 2026 and are intended to provide a sample of the state-of-the-art and highlight important research directions in a field of special interest to ICDEA 2026 participants. Each Special Session should be a focused effort rather than defined broadly.

Important Dates

Proposal submission deadline: 15th April 2026.

Proposal notification: 22nd April 2026

Requirements

The minimum target for each Special Session is 4 accepted papers.

The following information should be included in the proposal:

• Title of the proposed special session
• Names and affiliations of the organizers (including brief bio and contact info)
• Session abstract (state the motivation and significance of the topic, and the rationale for the proposed session)
• List of invited papers (including a tentative title, author list )

In addition to invited papers, other potential authors will be allowed to submit papers to Special Sessions. All papers will go through the same review process as the regular papers submitted to the main conference to ensure that the contributions are of high quality. 

Proposals will be evaluated based on the timeliness of the topic and relevance to ICDEA 2026, as well as the track record of the organizers and anticipated quality of papers in the proposed session. When considering submitting a Special Session proposal, please bear in mind that Special Sessions are expected to be oral sessions. Only those proposals that have the potential to attract high-quality papers are likely to be approved. Once the proposal has been approved, the organizer(s) and the Special Session co-chairs will arrange the review process.

Submission

Special session proposals should be submitted by email at : Rene.LOZI@univ-cotedazur.fr

 SS1

Advances in Dynamical Systems and Their Applications

Organizers: 

Yun Kang – Arizona State University, School of Mathematical and Statistical Sciences, Tempe, Arizona, USA.

Jaqueline Mesquita – Universidade Estadual Paulista (UNESP), Department of Mathematics, São José do Rio Preto, Brazil.

Sabrina Streipert – University of Pittsburgh, Department of Mathematics, Pittsburgh, Pennsylvania, USA

Abstract:  Our special session entitled “Advances in Dynamical Systems and Their Applications” focuses on recent advances in modeling complex systems arising in biology, social sciences, and related fields, and methods in discrete mathematics for their analysis and investigation. We particularly welcome contributions on discrete-time dynamical systems, network and agent-based models, as well as related frameworks such as abstract dynamical systems. The session aims to bring together researchers developing novel analytical methods particularly relevant when studying discrete models applied to real-world problems as well as researchers utilizing discrete mathematics to describe real-life processes. This session fosters an exchange of tools, techniques, and modeling perspectives. Topics of interest include, but are not limited to, stability and persistence theory, bifurcation phenomena, periodic behavior and its emergence, threshold dynamics, and the effects of nonlinear interactions and heterogeneity in models in ecology, epidemiology, social sciences, and beyond. By bridging methodological developments and practical applications, this session seeks to highlight the growing role of discrete dynamical approaches in addressing contemporary challenges across the life and social sciences.

Asymptotic behaviours of nonautonomous and random discrete dynamical systems

Organizers:

Davor Dragičević – Faculty of Mathematics, University of Rijeka, Rijeka, Croatia.

Adina Luminița Sasu – Department of Mathematics, West University of Timișoara, Timișoara, Romania.

Weinian Zhang – School of Mathematics, Sichuan University, Chengdu, Sichuan, People’s Republic of China.

Abstract: Asymptotic behaviors of dynamical systems have been among the most active areas of research in the past decades, with a substantial impact and remarkable applications in control theory, engineering, economics, biology, and computer science. This special session aims to highlight recent advances in the qualitative and quantitative asymptotic theory of discrete dynamical systems and difference equations, with a special focus on nonautonomous and random dynamical systems.  Topics to be considered will include exponential dichotomy, generalized dichotomy, exponential trichotomy, robustness, evolution semigroups, and limit theorems for nonautonomous and random dynamical systems. Among the methods to be discussed and explored, we mention control techniques, admissibility, shadowing, invariant sets, ergodic theory approaches, operator theory, and spectral properties. Other related topics of high impact in the same areas are welcome.

Advances in Mathematical Epidemiology at the Interface of Difference and Differential Equations and Ecological Dynamics (Online)

Organizers:

Chidozie Williams Chukwu – Department of Mathematical Sciences, Georgia Southern University Statesboro, Georgia, USA

Dawit Denu – Department of Mathematical Sciences, Georgia Southern University Statesboro, Georgia, USA

Folashade B. Agusto – Department of Ecology and Evolutionary Biology, University of Kansas Lawrence, Kansas, USA

Abstract:  Mathematical epidemiology has become an essential tool for understanding the spread and control of infectious diseases. Models based on differential and difference equations provide powerful frameworks for describing the nonlinear interactions among host populations, pathogens, and intervention strategies. At the same time, ecological processes, such as environmental variability, host–vector interactions, and population heterogeneity, play a fundamental role in shaping disease dynamics and must be incorporated to achieve more realistic models. This special session explores recent advances in epidemiological modeling at the intersection of dynamical systems and ecological processes. By integrating ecological drivers into mathematical frameworks, researchers can better capture the complexity of disease transmission in both human and animal populations. Topics of interest include differential and difference equation models, ecological drivers of transmission, vector-borne and zoonotic diseases, stability and bifurcation analysis, delay and fractional-order models, spatial and network dynamics, data-driven modeling and forecasting, and optimal control strategies. The session aims to bring together researchers in applied mathematics, mathematical biology, and epidemiology to share recent theoretical developments and practical applications. It seeks to foster interdisciplinary collaboration and highlight emerging directions in infectious disease dynamics.
