As part of the Oberseminar Mengenlehre,
**Vladimir Kanovei** will give an introduction to the Descriptive Set
Theory of Equivalence Relations. This area of Descriptive Set Theory has
mainly been developed by Kechris and Hjorth and is a very important area of
research connecting Descriptive Set Theory to other (non-logical) fields of
mathematics.

The course will consist of five lectures, given on the following dates:

October 26th, 2000 | Part I | SR B, 4 pm |

November 2nd, 2000 | Part II | SR B, 4 pm |

November 29th, 2000 | Part IV | SR C, 10 am |

In the Oberseminar on Thursday, Nov 30 (4 pm), Marc van Eijmeren will talk about a paper of Marcia Groszek and Ted Slaman that seems to be connected with Vladimir's talks.
