SUMMARY:Geometry and Topology Seminar: Homological representations of motion groups - Martin Palmer (Mathematical Institute of the Romanian Academy)
DESCRIPTION:Abstract: The Lawrence representations are an important family of representations of the braid groups. The first is the Burau representation and the second is the LKB representation\, which was used by Bigelow and Krammer to prove that the braid groups are linear (act faithfully on finite-dimensional vector spaces). The construction of...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10881

Interesting information about the underlying platonic solid can be discovered in the cover where more (dynamical and geometric) structure is present.

The Nielsen–Thurston classification of mapping classes is an analogous theorem in low-dimensional topology.

DESCRIPTION:Abstract: We introduce a new stable range invariant for the classification of closed\, oriented topological 4-manifolds (up to s-cobordism)\, after stabilization by connected sum with a uniformly bounded number of copies of S2 x S2.\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11026
