Abstract
In this paper we consider the extension of the classical Hamilton - Cartan variation theory to fibrous varieties. It is known that in field theory, we can assign various Hamiltonian equations corresponding to the Lepage equivalents of Lagrangian to the variational problem represented by Lagrangian. The case of affine Lagrangians in the second derivatives is studied using differential geometry tools. A new condition of regularity and strong regularity and Legendre's transformation are found.
Abstract (in Czech)
V příspěvku uvažujeme rozšíření klasické Hamiltonovy - Cartanovy variační teorie na fibrované variety. Je známo, že v teorii pole variačnímu problému reprezentovanému Lagrangiánem můžeme přiřadit různé Hamiltonovy rovnice koresponující s Lepageovými ekvivalenty lagrangiánu. Případ lagrangiánů afinních v druhých derivacích je studován za pomoci nástrojů diferenciální geometrie. Nalezeny jsou nová podmínka regularity a silné regularity a Legendrova transformace.
