Kurt Gödel Research Center

KGRC Research Seminar

In the KGRC Research Seminar, current research in Mathematical Logic is presented. Since its beginning in 1999, about 500 talks have been given, about half of them by visitors from outside Austria, including numerous leaders in the field. (We recently started another seminar as well, the Friday seminar.)
