In Carnot groups of step ≤ 3, all subriemannian geodesics are proved to be normal. The proof is based on a reduction argument and the Goh condition for minimality of singular curves. The Goh condition is deduced from a reformulation and a calculus of the end-point mapping which boils down to the graded structures of Carnot groups.
Keywords: subriemannian geometry, geodesics, calculus of variations, Goh condition, generalized Legendre-Jacobi condition
