We study different norms on the group of contactomorphisms of a contact manifold. For every integers n greater than 0, using generating function techniques, we characterise some geodesics of the group of compactly supported contactomorphisms of R2n x S^1 endowed with its standard contact structure. We compute explicitely the norm of a big family of contactomorphisms of the unitary cotangent of the torus using a theorem of intersections between exact Lagrangians with the 0-section inside the cotangent. Finally we study the characteristic distribution on hypersurfaces lying inside the contactification of an exact symplectic manifold. It allows us to define a new set of values for open domains of the contact manifold considered. This set of v...
