2013 Arne Magnus Lecture Series

The 2013 Magnus Lecture Series was held March 13-15, 2013. This year's guest speaker was Pascal Chossat, Director of Research in the Department of Mathematics at University of Nice and the French National Center for Scientific Research.

Dr. Pascal Chossat's public talk title was Bifurcation and symmetry, a mathematical view on pattern formation in nature. His research talk topic was related to Pattern formation and the bifurcation of heteroclinic cycles. His final colloquium talk for faculty, advanced graduate students and advisers focused on Pattern formation on compact Riemann surfaces and applications.

Dr. Pascal's biological sketch includes:
PhD part 1: 1978
PhD part 2: 1982 (part 2 is a kind of habilitation)
Both from University of Nice. Advisor: Gerard Iooss

1982: Research Fellow, Centre Nationale de Recherche Scientifique (French National Center of Scientific Research) in Nice, with affiliation to University of Nice
1989: Research Director of CNRS in Nice

Two 1-year visits in the US:
1988: University of Houston - collaborated with Marty Golubitsky on pattern formation
1998: University of California at Santa Cruz, collaborated with Todu Ratiu on Hamiltonian systems

Position of Scientific Counselor at the French Embassy in India. He and his wife lived in new Dehli during this time. (He wrote a paper about the dynamics of a pendulum with hexagonal shape that was hanging in the embassy and which he could watch every day.)

Director of CIRM (Centre International de Recherche de Mathematique -- a Mathematical Research Center like MSRI) in Marseille

Worked in Paris at the CNRS Headquarters in the position of Scientific Deputy Director in charge of international collaboration

Returned to Nice, continued as research Director of CNRS and became Director of the Federation of Physics and Mathematics Laboratories in Nice, which combines all Physics and math labs at CNRS and the University of Nice.

Research Areas:
Dynamical Systems, Bifurcation, Symmetry, Pattern Formation

Mathematically: He applies tools from Analysis, Geometry and Algebra to study Dynamical Systems, Instabilities and Bifurcations

Following the French tradition he consistently applied mathematical results to a variety of applied areas, in particular fluid mechanics and mathematical biology

Current focus of interest: Mathematical Neuroscience

The Arne Magnus Lectures are given annually in the Department of Mathematics at Colorado State University in honor of Dr. Arne Magnus, our friend and colleague for 25 years. The 2013 lectures were supported by the Arne Magnus Lecture Fund and the Albert C. Yates Endowment in Mathematics. Contributions to the Magnus Fund are greatly appreciated and may be made through the Department of Mathematics.
