SUMMARY:Geometry and Topology Seminar: A Stability Range for 4-Manifolds - Ian Hambleton (McMaster University)
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

SUMMARY:Geometry and Topology Seminar: Algebraic v/s geometric complexity of simple closed geodesics - Francisco Arana-Herrera (University of Maryland)
DESCRIPTION:Abstract: How homologically complicated are long simple closed geodesics on hyperbolic surfaces? We provide an answer to this question which is surprisingly different from the well studied case of general primitive geodesics. We explain the relation between these questions and mixing limit theorems for the Kontsevich-Zorich cocycle.

DESCRIPTION:Abstract: Beginning with simple examples\, my talk will introduce a novel approach to understanding Atiyah-Patodi-Singer indices for manifolds with boundary that casts them within the framework of an associated topological quantum field theory. This has applications in spectral geometry\, particularly to Floer-style gradings on moduli spaces.\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11065

DESCRIPTION:Abstract: We introduce a group Θ8(r ) consisting of polarised simply-connected 8-manifolds whose homology is isomorphic to that of the connected sum of r copies of S 2 x S 6. The group Θ8(r ) comes equipped with an action of GL(r\, Z) and a stabilisation map to Θ8(r + 1). We determine the isomorphism type of Θ8(r )\, and show...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11090

SUMMARY:Geometry and Topology Seminar: Mapping class groups of 4-manifolds via the Budney-Gabai invariants - Weizhe Niu (University of Glasgow)
DESCRIPTION:Abstract: According to the work of Budney-Gabai\, the smooth mapping class group of S1 × D3 is infinitely generated. Their construction is based on a special class of diffeomorphisms known as barbell diffeomorphisms. They use a rational homotopy invariant to detect an infinite sequence of linearly independent generators\, represented by certain barbell...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11203
