Some multidimensional integrable cases of nonholonomic rigid body dynamics
In this paper we study the dynamics of the constrained --dimensional rigid
body (the Suslov problem). We give a review of known integrable cases in three
dimensions and present their higher dimensional generalizations.Comment: 10 page
Noncommutative integrability and action-angle variables in contact geometry
We introduce a notion of the noncommutative integrability within a framework
of contact geometry.Comment: 22 pages,1 figure, Theorem 5 slightly modifie
Noether symmetries and integrability in time-dependent Hamiltonian mechanics
We consider Noether symmetries within Hamiltonian setting as transformations
that preserve Poincar\'e-Cartan form, i.e., as symmetries of characteristic
line bundles of nondegenerate 1-forms. In the case when the Poincar\'e-Cartan
form is contact, the explicit expression for the symmetries in the inverse
Noether theorem is given. As examples, we consider natural mechanical systems,
in particular the Kepler problem. Finally, we prove a variant of the theorem on
complete (non-commutative) integrability in terms of Noether symmetries of
time-dependent Hamiltonian systems.Comment: 18 pages, 2 figures, to appear in Theoretical and Applied Mechanic
