- Title: Insights into rational numbers through computation and geometry
- Location: Room V129, Mathematics Building (Callaghan Campus) The University of Newcastle
- Time and Date: 2:00 pm, Mon, 13th Dec 2010
- Abstract:
Rational numbers can be represented in many different ways: as a fraction, as a M"obius function, as a 2x2 matrix, as a string of L's and R's, as a continued fraction, as a disc in the plane, or as a point in the lattice Z^2. Converting between the representations involves interesting questions about computation and geometry. The geometries that arise are hyperbolic, inversive, or projective.
