Second variational derivative of local variational problems and conservation laws. (English) Zbl 1265.58008
The paper deals with topological aspects of conserved quantities which arise in correspondence of symmetries in field theories. Noether’s theorem is local in its nature; in the paper the more general problem of finding global conservation laws is addressed when there is no global Lagrangian to a given variational form.
