The momentum map in Vakonomic Mechanics
Under certain conditions on the constraint submanifold, the concepts of Cartan form and momentum map are introduced for vakonomic dynamical systems. We also stablish the relation of these notions with the corresponding ones derived by application of the Lagrange multipliers method. The theory is illustrated by three classical examples (the skateboard, the ball rolling on a surface and the generalized elastica), letting an insight into the differences between the vakonomic and  non-holonomic methods.
