Košice and Drienica were recently the setting for celebrations marking the 50th anniversary of the STROM seminar. Half a century ago, the KMS – Correspondence Mathematical Seminar was founded at UPJŠ in Košice; in 1993 it was renamed STROM and became the first mathematical seminar of its kind in Czechoslovakia. In 1995, the STROM Association was established, and has since overseen not only the STROM seminar but also the Matik and Malynár seminars – all three continue to run today, alongside a growing range of additional activities.
The official part of the celebrations took place in Košice on Friday, 26 June 2026.
