HAnDA Symposia are held in a hybrid format, facilitating communication among researchers and promoting the dissemination of research results on Algebraic Hypercompositional Structures and their applications. Moving beyond formal publications in journals or books, the Symposium seeks to maintain an ongoing and welcoming environment for pure research, fostering interdisciplinary influences and innovative developments. A core objective of HAnDA is to facilitate personal acquaintance and networking among researchers, encouraging the exchange of ideas and the cultivation of new collaborations within the scientific community.

The topics to be covered by HAnDA relate to all types of hypercompositional structures — such as hypergroups, hyperrings, hyperfields, hypermodules etc — as well as their applications to the theories of fuzzy, rough, and soft sets. Furthermore, the Symposium encompasses research in automata, formal languages, codes, cryptography, graphs, lattices, groups, differential equations, and geometry. Its scope also extends to diverse scientific fields, including engineering, chemistry, biology, economics, statistics, and information sciences.

The first HAnDA symposium was hosted in Thessaloniki in 2017, while subsequent editions have been conducted in a hybrid format. HAnDA is co-organized by the University of Nova Gorica (Slovenia) and the National and Kapodistrian University of Athens.

This year’s symposium will take place from May 25–29, 2026. Participants are kindly requested to confirm their participation by sending the title and abstract of their presentation to: irina.cristea@ung.si and chrmas@uoa.gr. The link for attending the symposium will be sent to participants via email.
