| dc.description.abstract | Two examples of Diff⁺S¹-invariant closed two-forms obtained from forms on jet bundles, which does not admit equivariant moment maps are presented. The corresponding cohomological obstruction is computed and shown to coincide with a nontrivial Lie algebra cohomology class on H²(X(S¹)). | uk_UA |
| dc.description.sponsorship | This paper is a contribution to the Special Issue “Elie Cartan and Differential Geometry”. Part of this work started during the stay of the first author at Utah State University under the advice of Professor Ian Anderson. The computations were first obtained by using MAPLE package “Vessiot”. Supported by Ministerio de Ciencia e Innovaci´on of Spain under grant #MTM2008–01386. | uk_UA |
