Topic of Math colloquium May 10 is ‘Geometric Integration of Multibody Systems’

Debra Lewis of the University of Minnesota will speak on “Geometric Integration of Multibody Systems” on Wednesday, May 10. Her talk is part of the Center for Applied Mathematics Colloquium Series that introduces members of the University of St. Thomas community to a variety of problems, careers and professional activities involving applications of mathematics.

All presentations in this series are held at 3 p.m. Wednesdays in the 3M Auditorium, Owens Science Hall, Frey Science and Engineering Center, located at the southwest corner of Summit and Cretin avenues. Refreshments will be available at 2:45 p.m.

About the discussion 

Geometric integration schemes preserve certain key features (e.g., energy, symplecticity and symmetries) of a dynamical system to higher precision – often exactly – than the overall order of the algorithm. Such methods are of particular interest in situations where traditional high-order methods are not feasible or cost effective.

The geometric structures of multibody systems derived from variational principles play a crucial role in classical analyses of such systems and appear to be critical in numerical simulations as well.
