 Special Lecture

Date: October 18, 2005 16:30-18:00

Venue: Room 309, Building 8, Department of Mathematics, Faculty of Science, Hokkaido University

Organizer: G. Ishikawa

Speaker: Professor M. Zhitomirskii (Department of Mathematics, Technion, Haifa, Israel)

Title: THE HOMOTOPY METHOD

Comment:

I will try to explain, basing on many examples, that this method and its modifications is a very powerful tool. Of course, this talk can be made informal if there will be only few people interested in it.
