Pure Maths Colloquium: Quadratic forms in topology
16 January 2012 16:00 in CM221
Quadratic forms have a great importance and ubiquity in many areas of mathematics, notably in algebraic and geometric topology. This talk will focus on a particular instance of this: a quadratic form associated to a knot by Goeritz in 1933. The aim is to give a gentle introduction to some current work in knot theory making use of the Goeritz form.
