Abstract:
The construction of the ball of small radius in Sub-Riemannian geometry shows the importance of Lagrangian stratifications when there exists abnormal geodesics. We discuss this stratification using the example of Martinet SR geometry. We show that such a stratification is also related to the computations of limit cycles in 16-th Hilbert problem.
