THE FIELDS INSTITUTE FOR RESEARCH IN MATHEMATICAL SCIENCES

October 14-17, 2014

Workshop on Moment Methods in Kinetic Theory II
Fields Institute, 222 College St., Toronto

Organizing Committee
Clinton Groth (Toronto), James McDonald (Ottawa), Shi Jin (Wisconsin)

OVERVIEW

The workshop is a follow-on to the previous and very successful workshop on "Moment Methods in Kinetic Gas Theory" that was held hosted at the Eidgen össische Technische Hochschule (ETH) in Zürich, Switzerland from November 6-8, 2008. Like its predecessor, the Fields workshop will bring together leading researchers, mathematicians, scientist, and engineers, at all academic levels, involved in the theory, development, application, and solution of moment closures arising from kinetic theories. Researchers involved in direct solution of kinetic descriptions will also participate. The workshop will focus on recent advances in the mathematical theory of moment closures, advanced numerical solution methods for their solution, and the application and evaluation of moment method techniques for a range of problems, including new applications in social sciences and biology.
The workshop is sponsored by the Fields Institute, KI-Net (an NSF Research Network in Mathematical Sciences), University of Ottawa Faculty of Engineering, University of Ottawa Department of Mechanical Engineering, University of Toronto Faculty of Applied Science and Engineering, and the University of Toronto Institute for Aerospace Studies.
