SUMMARY:Moving frames and the calculus of variations: analytical and numer
 ical solutions up to dimension 2 - Michele Zadra (University of Kent)

DESCRIPTION:In this talk I will give a gentle introduction to the theory o
 f moving frames and its applications to the calculus of variations. Throug
 h the use of some simple running examples\, I will show how the moving fra
 mes machinery can make life very easy when we have to deal with 1D Lagrang
 ian that possesses a Lie group symmetry. In the second part of the talk I 
 will present a conjecture we have been trying to solve\, regarding the use
  of Lie group integrators in order to numerically solve 2D variational pro
 blems. If time permits\, I'll finish giving some information about how the
  smooth and discrete cases can be treated in a single more general setting
 .
