Report on coalgebraic methods in computer science 2022

The 16^th edition of the IFIP WG 1.3 International Workshop on Coalgebraic Methods in Computer Science (CMCS 2022) took place in Munich on Saturday April 2 and Sunday April 3, 2022, as a satellite event of the European Joint Conference on Theory and Practice of Software (ETAPS 2022). As chairs of the workshop, it was a great pleasure for us to run the workshop as an on-site event after a long hiatus due to the COVID pandemic. The workshop was, in fact, a hybrid event, allowing both speakers and registered participants to participate remotely, but in-person participation was strongly encouraged, partly through ETAPS registration fees being the same for online and on-site participation. Up until just a few weeks before the workshop, the COVID situation in Munich was still quite uncertain, and we did not know how many people would attend on-site or at all, so we were extremely happy to find that the large majority of speakers and participants chose to travel to the event, which ensured a lively and engaging atmosphere. The workshop had circa 40 participants of which 5 participated online (with an attendance of 20--30 throughout the sessions). This made CMCS the second-largest workshop at ETAPS 2022. The hybrid setup did pose some technical challenges, but it was much appreciated, and without the option of presenting on-line at least three of the talks would have had to be cancelled. A hybrid format will be considered also for future editions of the workshop.
