Bi-Hamiltonian structure and peculiarities of mapping of the Lagrange top moment / M. A. Tuzhilin. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 2. P. 23-27 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 74-78].

A new approach to the problem of describing the singularities of the momentum mapping for the Lagrange top is presented in the paper. Previous results were obtained with the use of the bi-Hamiltonian structure. A simple and convenient technique for determination of singular points and their type is presented.

Key words: Lagrange top, bi-Hamiltonian structure, stability problem.
