SUMMARY:Geometry and Topology Seminar: The complementary regions of embeddings of 3-manifolds in S^4 - Jonathan Hillman (University of Sydney)
DESCRIPTION:Abstract: If a closed 3-manifold $M$ embeds in $S^4$ and is not an homology sphere it has infinitely many embeddings\, distinguished by the fundamental groups of the complementary regions. In order to apply surgery to study embeddings of 3-manifolds in $S^4$ we must restrict the groups that arise. If $M$ has...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11490

SUMMARY:Geometry and Topology Seminar: Quantitative Discrete Homotopy Theory - Emily Roff (University of Edinburgh)
DESCRIPTION:Abstract: "Discrete homotopy theory" refers to the use of homotopy-theoretic concepts and tools to study combinatorial structures such as graphs. The standard approach admits a quantitative variant\, in which one tracks the lengths of homotopies between maps\, leading to an infinite hierarchy of homotopy theories for graphs.

DESCRIPTION:Abstract: Smooth embeddings of manifolds into higher dimensional manifolds have been actively studied for many years. In this talk we concentrate on 3-dimensional lens spaces. It is known that they embed into 5-dimensional space\, so the interesting question regards embeddings into 4-dimensional manifolds. A homological argument proves that lens spaces...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11496

SUMMARY:Geometry and Topology Seminar: Hatcher-Wagoner invariants for half-unknotted barbell diffeomorphisms - Xiayu Tan (Tsinghua University)
DESCRIPTION:Abstract: In this talk\, we briefly recall the general definition of implanted (i\,n-i)-barbell diffeomorphisms and try to detect the non-triviality of a half-unknotted barbell diffeomorphism by associating it with a specific pseudo-isotopy (denoted as standard barbell pseudo-isotopy) and compute its Hatcher-Wagoner invariants explicitly. We give explicit formulae for (2\, n-2)-barbells and...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=11680
