Welcome to the ESI

The Erwin Schrödinger International Institute for Mathematics and Physics (ESI) is a programme-oriented research institute for mathematics and physics at the University of Vienna. Since its opening in 1993 it has been the mission of the ESI to advance research in mathematics and physics through fruitful interaction between scientists from these disciplines. [more]
