DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GEOTOP-A/78/
 ">Continuous topological measures: helicity\, winding\, and higher order w
 inding</a>\nby Mitchell Berger (University of Exeter) as part of GEOTOP-A 
 seminar\n\n\nAbstract\nMany measures of topological complexity are discret
 e: for example the linking number between two closed curves is an integer.
  However\, some topological invariants can be continuous. The winding numb
 er of two curves extending between parallel planes\, with fixed end points
  provides a simple example. We will discuss how winding numbers work in mo
 re complicated geometries such as spheres\, cubes\, and closed surfaces in
  general. On the way\, we will need Gauss-Bonnet. Also we will touch on hi
 gher order winding related to the Borromean rings.\n
