2. Internet Seminar 1998/99 - Spectral Theory and Asymptotic Behavior of Semigroups
In the academic year 1998/99, the TULKA group has organized an Internet Seminar on Spectral Theory and Asymptotic Behavior of One-parameter Semigroups. It was a great success with over 50 participants from Czech Republic, Germany, Great Britain, India, Italy, Japan, Morocco, Spain and USA.
After an electronic learning course the organization
team from Tübingen organized a final workshop
at the Heinrich-Fabri Institut in Blaubeuren.
