Zavádíme diferenciální systémy asociované s Eulerovými-Lagrangeovými rovnicemi na fibrovaných varietách a studujeme jejich symetrie a zákony zachování (cs)
We introduce exterior differential systems associated with Euler-Lagrange equations on fibred manifolds and investigate their symmetries and conservation laws.
