2. c^k-approximations and contactomorphisms


    1. Add remark

      Problem 2.1.

      Can hypersurfaces be c^\infty-approximated by Weinstein convex hypersurfaces?


        • Add remark

          Problem 2.2.

          [Eliashberg] For what k can we c^k-approximate the mapping tori of ergodic time-1 flows of contact vector fields by a contactomorphism whose mapping torus is convex?
