Beckman Hall

Speaker: Prof. Arek Goetz, San Francisco State University. The talk, accessible to nonprofessionals, will lead the audience into an exciting journey of the beauty of geometric structures obtained using computational mathematics derived from discontinuous dynamical systems that arise from problems in electrical engineering. We illustrate how rigorous computational mathematics and elementary number theory is used, producing fractal structure of piecewise isometries. Key words: fractals, computational mathematics, cyclotomic fields, dynamical systems, digital filters, piecewise isometries, computers producing publishable papers. Arek Goetz is professor of mathematics at San Francisco State University. An active researcher in dynamical systems, software architect and an educator, he has delivered over 90 talks on 5 continents. He is a recipient of two National Science Foundation Grants, as well as numerous teaching grants.
