Abstract:
We prove that in a class of non-equiregular sub-Riemannian manifolds corners are not length minimizing. This extends the results of $[4]$. As an application of our main result we complete and simplify the analysis in $[6]$, showing that in a $4$-dimensional sub-Riemannian structure suggested by Agrachev and Gauthier all length-minimizing curves are smooth.
