The tradition of the Czechoslovak Equadiff dates back to 1962 when Equadiff 1 took place in Prague. Subsequent Czechoslovak Equadiff conferences were held in Prague (1977, 1989, 2001, 2013), Bratislava (1966, 1981, 1993, 2005, 2017), and Brno (1972, 1985, 1997, 2009). All proceedings from these conferences are available via Czech Digital Mathematics Library. The Western Equadiff conferences were held in Marseille (1970), Brussels/Louvain-la-Neuve (1973), Firenze (1978), Wurzburg (1982), Xanthi (1987), Barcelona (1991), Lisboa (1995), Berlin (1999), Hasselt (2003), Vienna (2007), Loughborough (2011), Lyon (2015), and Leiden (2019). Equadiff is therefore one of the oldest active series of mathematical conferences in the world. The coming Equadiff in Brno in summer 2022 will be the 15th conference within the Czechoslovak Equadiff series. The conference was rescheduled to the year 2022 from the original date in July 2021 due to an unstable pandemic situation in the world.

The conference Equadiff 15 is organized by joint efforts of the following institutions:

• Masaryk University (Faculty of Science),
• Brno University of Technology (Faculty of Mechanical Engineering),
• Czech Academy of Sciences (Institute of Mathematics),
• The Union of Czech Mathematicians and Physicists (Brno branch)
