DESCRIPTION:James Montaldi (Manchester)\nHamiltonian Dynamics Seminar\nAbs
 tract: A choreography is a solution of the N-body problem where the N bodi
 es follow each other at regular intervals around a single closed path. Sin
 ce Chenciner and Montgomery's (re)discovery of the figure-8 choreography i
 n 2000\, there has been considerable interest in finding new ones.  The a
 pproach is usually to use variational methods on the appropriate loop spac
 e and the proofs have been a combination of symmetry arguments and analysi
 s. In this talk I will describe a complete classification of all the possi
 ble symmetry groups arising in this problem (there will be no analysis!). 
 It is joint work with my PhD student Katrina Steckles.
