International Conference in Honor of Nikolaos Limnios

The 5ᵗʰ International Symposium on Semi-Markov Processes and Applications 2026 (SMP2026) is an international scientific conference devoted to recent theoretical advances, methodological developments, and applied research in the broad field of semi-Markov processes and related stochastic models. This edition of the symposium is organized in honor of Professor Nikolaos Limnios, whose seminal and sustained contributions have profoundly shaped the theory of Markov renewal processes, semi-Markov processes, and their statistical and applied aspects.

The symposium aims to provide a high-level forum for researchers, academics, and doctoral students working in probability theory, stochastic processes, statistical inference, and applied stochastic modeling. It fosters the exchange of ideas between theoretical developments and practical applications, highlighting the central role of semi-Markov modeling in contemporary stochastic systems.

Dates
Deadline for Registration: April 9, 2026
Deadline for Abstract submission: April 9, 2026
Conference Dates: May 19-22, 2026

The scientific program of the symposium covers, but is not limited to, the following topics:

• Markov renewal processes and their theoretical foundations
• Semi-Markov processes and their generalizations
• Hidden semi-Markov chains and inference methodologies
• Semi-Markov random evolutions and related dynamical systems
• Reward and performance processes associated with semi-Markov models
• Limit theorems and functional limit theorems for semi-Markov processes
• Switching semi-Markov processes in stochastic and hybrid systems
• Controlled and decision-based semi-Markov processes
• Statistical inference, estimation, and testing for semi-Markov models
• Applications of semi-Markov processes and related stochastic frameworks

The primary objective of SMP2026 is to promote advances in the theory and applications of semi-Markov processes, while encouraging interdisciplinary interactions among mathematicians, statisticians, and applied scientists. Particular emphasis is placed on rigorous probabilistic analysis, modern statistical methodologies, and innovative applications arising in fields such as reliability theory, queueing systems, finance, biology, engineering, telecommunications, and operations research.

By honoring Professor Nikolaos Limnios, the symposium also seeks to acknowledge the profound impact of his work on the development of semi-Markov theory and its dissemination within the international scientific community. Through invited lectures, contributed talks, and focused discussions, SMP2026 aims to stimulate new collaborations and to identify emerging directions in semi-Markov research.

A Special Issue of MCAP will be dedicated to SMP2026 — The 5th International Symposium on Markov and Semi-Markov Processes and Related Fields: Theory and Applications.
