Kurzbeschreibung
LernzielZiel des Seminares ist zu lernen wie man Mathematik vortraegt. Als
Vorlage fuer dieses Seminar dient das Buch von Aigner und Ziegler "Proofs from the BOOK"
das aus allen Gebieten der Mathematik fundamentale Saetze und deren "schoensten" Beweise
praesentiert. Die Auswahl der Themen ist also gross und es gibt etwas fuer jeden Geschmack.
Vortraege koennen auf Deutsch, Franzoesisch oder Englisch gehalten werden.
401-4531-66LTopics in Rigidity Theory6 KP3GM. Burger
KurzbeschreibungThe aim of this course is to give detailed proofs of Margulis' normal subgroup theorem and his superrigidity theorem for lattices in higher rank Lie groups.
LernzielUnderstand the basic techniques of rigidity theory.
InhaltThis course gives an introduction to rigidity theory, which is a set of techniques initially invented to understand the structure of a certain class of discrete subgroups of Lie groups, called lattices, and currently used in more general contexts of groups arising as isometries of non-positively curved geometries. A prominent example of a lattice in the Lie group SL(n, R) is the group SL(n, Z) of integer n x n matrices with determinant 1. Prominent questions concerning this group are:
- Describe all its proper quotients.
- Classify all its finite dimensional linear representations.
- More generally, can this group act by diffeomorphisms on "small" manifolds like the circle?
- Does its Cayley graph considered as a metric space at large scale contain enough information to recover the group structure?
In this course we will give detailed treatment for the answers to the first two questions; they are respectively Margulis' normal subgroup theorem and Margulis' superrigidity theorem. These results, valid for all lattices in simple Lie groups of rank at least 2 --like SL(n, R), with n at least 3-- lead to the arithmeticity theorem, which says that all lattices are obtained by an arithmetic construction.

Voraussetzungen / BesonderesFor this course some knowledge of elementary Lie theory would be good. We will however treat Lie groups by examples and avoid structure theory since this is not the point of the course nor of the techniques.
