The Mathematical Center in Akademgorodok and the Chair of Geometry and Topology invite you to participate in an online seminar "Geometry, topology and their applications". Head of the seminar — I. A. Taimanov.
The seminar will take place on November 16
(UTC+7). S. O. Ivanov
(Saint Petersburg State University, Saint Petersburg) will present his talk "Localization and completion of groups and spaces"
The talk will present the theory of localization and completion of spaces, developed by Bousfield, Kan and others, as well as the theory of R-good spaces. It will be shown how this theory is related to a similar theory for groups and presented the results of the speaker in this area, obtained jointly with R. Mikhailov. In particular, we show that the wedge of two circles is a ℚ-bad space, which is the first example of a ℚ-bad finite CW-complex.
