DOCTORAL CLASS on MODERN MATHEMATICS FOR CONTEMPORARY SOUND MODELING and Image Processing

September. 28 - 30 , November 2004 Organized by the Vision, Image Processing and Sound Laboratory Department of Computer Science, University of Verona, Italy in collaboration with Sense-to-Sound, Sound-to-Sense (http://www.s2s2.org)

Contents

1. Tuesday, sept. 28, 14.00 -- 17.00 Giandomenico Orlandi (Univ. Verona): Mathematical Preliminaries.
Basic ideas in calculus, topology, differential geometry, and variational calculus.

2. Tuesday, sept. 28, 17.00 SEMINAR: Georg Essl (Medialab Europe, Dublin) Topological Ideas in Sound Synthesis.
How does a traffic roundabout, a detour and a traffic jam relate to sound synthesis? Why is this like gluing together a few rubber bands? In this seminar I hope to describe ideas of topology and how they can be translated into ideas to create structures for sound synthesis. By emphasizing the notion of periodicity and coincidence the topology of street layout can be turned into a sounding structure. We will illustrate how some of these ideas relate to sound generated by physical structures and how it is potentially different.

3. Wednesday, sept. 29, 9.00 -- 12.00 Georg Essl (Medialab Europe, Dublin): Topology and Dynamical Systems.
The wave equation in 1 and 2 dimensions. Geometric optics. Rays, eikonal, orbits, billiards, caustics, short wave asymptotics.

4. Wednesday, sept. 29, 14.00 -- 17.00 Georg Essl (Medialab Europe, Dublin): Geometry of Wave Phenomena
