Názov: Approximations of discrete groups by finite ones
Termín: 17.3.2016, 9:50 hod., M/213
Abstrakt:
The plan of my talk is as follows:
- Almost homomorphisms and approximations of groups.
- Metric approximations of discrete groups. Topological approximations. Equivalent denitions.
- Soc groups. Hyperlinear groups. Weakly soc groups. Linear soc groups.
- Equations over groups. Kervaire-Laudenbach conjecture.
- SQ-universality, congruence extension property, and socity. The nonstandard extension of a free group.
- If time permits I will touch the approximations of topological groups.
