Relative equilibria in mechanical systems with isotropy
Wednesday 18th, August 14:05-14:55pm,
Carslaw Lecture Theatre 273.
Given a mechanical system with a symmetry group acting on it,
symmetric points in configuration space are points with
non-trivial isotropy subgroups. Generally, at this points, the
reduced space is not a manifold.
Using a version of the slice theorem and given a Lagrangian
function, we offer a constructive method to compute the equations
of motion and the relative equilibria conditions in a model space
based at a symmetric point. We compare our results with previous
developments and apply them to simple mechanical systems. This
work is joint with Mark Roberts (Surrey) and Tanya Schmah (Macquarie).
