UNIVERSITY OF WATERLOO FRACTAL GEOMETRY AND DYNAMICAL SYSTEMS SEMINAR SERIES ===================================================== TITLE: Quaternionic Julia Sets SPEAKER: Prof. John Holbrook, University of Guelph DATE: Thursday, March 24, 1988 ^^ [Note change of date] TIME: 3:30 p.m. ROOM: MC 1056 ABSTRACT: The quaternions provide a four-dimensional playground in which one can mimic some of the constructions and concepts from complex dynamics in a hypercomplex setting. We examine the quaternionic analogues of Julia sets (fractal dragons and the like) for quadratic mappings and demonstrate methods for displaying the resulting 4D dragons. We consider questions of symmetry and connectedness for these objects. We may ask for a sort of atlas or Mandelbrot set for classifying the objects in terms of the quaternionic parameter value.
