Central European Seminar is a semiperiodic event devoted to Differential
Geometry initiated by Peter Michor about 20 years ago. From a small seminar
of a group of geometers in Vienna and Brno (notably Ivan Kolar, Peter
Michor, their students and some more) this event has evolved to a vital
meeting point of many geometers in particular from Vienna, Brno, and Prague.
The representative contact persons involve Andreas Cap, Jan Slovak, Vladimir
Soucek.
