SUMMARY:Geometry and Topology Seminar: Embedding spaces of split links - Rachael Boyd (University of Glasgow)
DESCRIPTION:Abstract: This is joint work with Corey Bregman. We study the homotopy type of embedding spaces of unparameterised links\, inspired by work of Brendle and Hatcher. We obtain a simple description of the fundamental group of the embedding space\, which I will describe for you. Our main tool is a semi-simplicial...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10986

SUMMARY:Geometry and Topology Seminar: The universal structure of moment maps in complex geometry - Ruadhaí Dervan (University of Glasgow)
DESCRIPTION:Abstract: Much of complex geometry is motivated by linking the existence of solutions to geometric PDEs (producing "canonical metrics") to stability conditions in algebraic geometry. I will answer a more fundamental question: what is the recipe to produce geometric PDEs in complex geometry? The solution to this will use some old...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10985
