A Study of Some General Problems of Dieudonné-Rashevski Type

الملخص EN

We use a method of investigation based on employing adequate variational calculus techniques in the study of some generalized Dieudonné-Rashevski problems.

This approach allows us to state and prove optimality conditions for such kind of vector multitime variational problems, with mixed isoperimetric constraints.

We state and prove efficiency conditions and develop a duality theory.
