Moving Frames
Elizabeth Mansfield University of Canterbury, Kent, England

Abstract In this talk I will give a discussion of group based moving frames and discuss how they are used to ease the integration of ODEs with a Lie group symmetry, with expository examples and with particular reference to the Chazy Equation, a 3rd order ODE with an SL(2) symmetry. (Note that classical methods to integrate ODEs with a symmetry work best for solvable Lie groups, which SL(2) is not.)
