Date: Wed, Dec 2 2009

Location: Doppler Institute for Mathematical Physics and Applied Mathematics, Prague

Speakers: Pavel EXNER

It is a longstanding problem how to understand the coupling in vertices of
a quantum graph using an approximation by a family of appropriate fat
graphs\. In particular, it is known that if the approximating operators are
