DESCRIPTION:Speakers: Christopher Douglas (University of Oxford)\n\nMPIM T
 opology Seminar\nDo you have a favorite smooth manifold? Would you like a 
 combinatorial model of it? Then embed it in euclidean space and wiggle it 
 suitably. The result is called a tame tangle. We show that such generic em
 beddings are classified (up to framed ambient homeomorphism) by a combinat
 orial structure called a tangle truss. We hypothesize that suitable wiggle
 s always exist and that the resulting tangle truss faithfully encodes the 
 smooth structure of the manifold.\nI will give a light and informal overvi
 ew of framed combinatorial topology (gradually working up to tame tangles 
 and tangle trusses)\, illustrated by images from a new book on the subject
 \, with Christoph Dorn.\n\nhttps://math-events.uni-bonn.de/event/1583/
