PERIPATETIC SEMINAR ON SHEAVES AND LOGIC 84th meeting - first announcement Dear Colleagues, The 84th meeting of the seminar will be held at the Department of Theoretical Computer Science of the Technical University Braunschweig, Germany, over the weekend of October 14-15, 2006. As always, he seminar welcomes talks using or addressing category theory or logic, either explicitly or implicitly, in the study of any aspect of mathematics or science. Following the positive experience at PSSL83 in Glasgow earlier this year, Samson Abramsky and Bob Coecke have agreed to jointly give a three talk overview of recent developments in the categorical approach to quantum informatics. We hope that professor Reinhard Werner, mathematical physicist at the TU Braunschweig with special interest in quantum informatics, can be present as well. Braunschweig is located about 60 km East of Hannover and about 200 km West of Berlin. It can easily be reached by car or train. The closest airport is in Hannover; the airport bus to the Hannover train station takes about 20 minutes, and the train from there to Braunschweig takes about 40 minutes or less. Further information on the location of the seminar, along with details on local travel and accommodation together with an online registration form can be found at http://www.iti.cs.tu-bs.de/TI-INFO/koslowj/PSSL84.html Best regards, Jiri Adamek J=FCrgen Koslowski Stefan Milius --=20 Juergen Koslowski If I don't see you no more on this world ITI, TU Braunschweig I'll meet you on the next one koslowj@iti.cs.tu-bs.de and don't be late! http://www.iti.cs.tu-bs.de/~koslowj Jimi Hendrix (Voodoo Child, SR)
