THE LEVICH INSTITUTE ANNOUNCES THE FOLLOWING SEMINAR:

Tuesday, 10/13/98
4:00 PM
Steinman Hall, Room #1M-22
Professor Andreas Dress
University of Bielefeld (Germany)
Mathematics Department
"Visualization of Fluid Dynamic Systems"


ABSTRACT

I will report on visualization techniques developed by Peter Serocka for exploring a given numerical solution of the Navier-Stokes equation of the 2D-paradigm of laminar fluid motion in a channel around a vortices-creating circular obstacle. Peter's software allows, in particular, to approximate the generally highly non-connected, strongly non-stable and strangely intertwined 1D area in 3D spacetime consisting of the union of all periodic orbits of the given system. Some open mathematical problems arising from such explorations will also be addressed.

BRIEF ACADEMIC/EMPLOYMENT HISTORY:

PhD: 1962, U Kiel, subject: number theoretic problems, related to the geometry of reflections Habilitation: 1965, U Kiel, subject: a local-global principle for certain (in general non-discrete) groups

After working as a "Wissenschaftler Rat" at the FU Berlin from 1965 -- 1967 and spending the academic years 1967/8 and 1968/9 as a visiting member at the Institute for Advanced Studies in Princeton, I followed a call to join the Mathematics Department of the newly founded U Bielefeld in 1969 where I am working still, interrupted of course by many shorter or longer visits to many universities and research institutions (e.g.IAS Princeton, Queen Mary College London, IBM Heidelberg, ETH Zurich, Mittag Leffler Institut Stockholm, Scripps Research Institute (La Jolla), RIMS (Kyoto), the University of Canterbury, New Zealand, and presently CUNY, to name just a few). In 1990, I got a call to the Technical University Berlin and, in 1992, another one to the RWTH (Aachen), both of which I finally had to decline.

RESEARCH INTERESTS:

Present research interests range from scientific visualization to classical algebra (in particular: axiomatic representation theory) and include various areas of applications of combinatorics and discrete mathematics in optimization theory, crystallography, chemistry and biology.
