Dear all, We are pleased to announce that the first Central European Category Theory Seminar will take place at Masaryk University, Brno on Friday November 20th 2026. The idea of the meeting is to bring together researchers in category theory and related areas from around the local region in an informal setting to meet and discuss their research. We have invited speakers from Prague, Vienna and Budapest and will also welcome short contributions from attendees. Further information is available on the webpage. https://centraleuropeanctseminar.github.io/CECTSeminarBrno2026/ Anyone is welcome to attend but we ask you to register by September 30th so we have an idea of the numbers. This is essential if you would like to contribute a short talk or apply for some financial support to make the trip (we expect to have some money available for train/bus transport and hotel). If you have any questions, feel free to email any of the organisers. Look forward to seeing you there, The Organisers (John Bourke, Mike Lieberman, Lukas Vokřínek).
