报告摘要:
A sub-Riemannian problem is an optimal control problem with a quadratic cost functional,for a linear in control system. Geometric control theory provides efficient techniques for detailed study of such problems.
The talk will be devoted to the following questions:
- sub-Riemannian structures,
- rank controllability condition,
- Filippov's theorem,
- Pontryagin maximum principle,
- sub-Riemannian geodesics, local and global optimality,
- conjugate points and cut points,
- symmetries and Maxwell points,
- examples of solved problems (Heisenberg group, SO(3), SL(2), SE(2), Engel group),
- applications (cars with trailers, rolling bodies, image inpainting).
