#FICS23 (International Workshop on Fixed Points in Computer Science), which runs alongside
#CSL2023 , "is to bring together people from different fields such as algebra/coalgebra, verification, logic, around the thematic of fixed points". No proceedings, but "Depending on the nature of the contributions, a special issue of
#FundamentaInformaticae might be published with selected contributions".
#FixedPoint I couldn't find a website but here is a web link to the call:
