Abstract:
We compare and contrast two approaches to the structure theory for Lie pseudo-groups, the first due to Cartan, and the second due to the first two authors. We argue that the latter approach offers certain advantages from both a theoretical and practical standpoint.
Keywords:
Lie pseudo-group; infinitesimal generator; jet; contact form; Maurer–Cartan form; structure equations; essential invariant.
