Abstract
Reduction for Lagrangians which are quasi invariant under the action of a group G is discussed in the framework of Pfaffian Systems. In this geometrical setting the reduction of quasi invariant Lagrangians is performed by using first integrals and residual symmetries both in the Abelian and in the non Abelian case.
