Integer lattices of action variable for the generalized Lagrange case / E. O. Kantonistova. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2012. № 1. P. 54-58 [Moscow Univ. Math. Bulletin. Vol. 67, N 1, 2012.].
In this paper we construct lattices generated by integer-valued isolines of action variables of some integrable Hamiltonian systems with two degrees of freedom (generalized Lagrange case). The monodromy matrices for critical points of this system are calculated.
Key words: Hamiltonian monodromy, action variables, integrable Hamiltonian systems, rigid body.
