Abstract: A thrackle is a drawing of a finite graph in which every pair
of edges meet exactly once, either at a common vertex or at a transverse
crossing. The pentagram is a simple example. This talk outlines joint
work with Yury Nikolayevsky in which we use homologocal ideas to
examine Conway's thrackle conjecture.
