About Us

HAnDA aims to be the natural progression in the dissemination of research findings on Algebraic Hypercompositional Structures and their Applications, beyond formal publications. It welcomes pure research, interdisciplinary influences, and applications in various fields, including hypercompositional structures like hypergroups, hyperrings, hyperfields, hypermodules etc, and their applications to the theories of fuzzy, rough and soft sets, automata, formal languages, codes, cryptography, graphs, lattices, differential equations, geometry as well as engineering, chemistry, biology, economics, statistics, information sciences, and so on.

About the event

The inaugural HAnDA was held in Thessaloniki, Greece, 2017 and the next ones were hybrid. They are organized by the University of Nova Gorica, Slovenia and the National and Kapodistrian University of Athens, Greece. This year's symposium will be held online via the MiTeam platform from June 2 to June 6, 2025. A participation link will be sent via email to the attendees who have been confirmed in advance at irina.cristea@ung.si, ch.massouros@gmail.com. Authors are kindly invited to send the title and an abstract of their presentation to the aforementioned email addresses.
