Mathematical preliminaries

  • Introduction of an affine space
  • Then, defines a Lie group on the displacement
  • Then defines the Klein form, a bilinear, symmetric, non-degenerate form, invariant by applying the adjoint map, plays a crucial role in energy-related aspect. Treat the equation of beams with the first level: using the Lie algebra
