Central European Seminar, Brno, 15 December, 2023

This very traditional seminar was founded by Peter Michor (Vienna) and Ivan Kolář (Brno) in 1985 and it has been active (with short breaks) since then.

Nowadays, the seminar is based on close collaboration of mathematicians and mathematical physicists from Vienna, Prague, and Brno and serves as wider international networking platform meeting about four times a year.

This time, the program displayed three contribution:

• Petr Vlachopulos: Eigenvalue flow on minimal hypersurfaces in S^n

• Radek Kycia:  Topological duals of exact/anti-co-exact forms

• Jan Gregorovic: Models of 2-nondegenerate CR hypersurfaces
