Dear friends of intuitionistic fuzzy sets and their applications!

We cordially invite you to the International Workshop on Intuitionistic Fuzzy Sets, which was founded by Prof. Beloslav Riečan in Banská Bystrica in 2005. The workshop will be held on December 12, 2025, online via platform MS Teams. The presented contributions will be published as part of Notes on Intuitionistic Fuzzy Sets/31/4|Volume 31, Number 4]] of International Journal Notes on Intuitionistic Fuzzy Sets. Participation in the workshop will be free of admission fee.
If you are willing to attend the Workshop, please send an email to:
- RNDr. Katarína Čunderlíková, PhD., MÚ SAV BB
- cunderlikova.lendelova@gmail.com
to obtain a link to the MS Teams session.
