Title: On classification of left-invariant sub-Riemannian structures 
over (2,3,4)-distribution.

Abstract: We obtain the full classification of left-invariant 
sub-Riemannian structures on Engel distribution. The rigidity of the 
sub-Riemannian structure in this particular case allows us to construct 
the unique up to an action of a finite group canonical frame. Then using 
elementary deformation theory we obtain fundamental system of invariants 
from the structure constants of the canonical frame. This essentially 
leads to the full classification of left-invariant sub-Riemannian 
structures over Engel distribution.

Venue: Wednesday 11 November at 2 pm in lecture room 133
