Vi. Orekhov, DUAL PARAMETRIZATION OF THE BIFURCATION SET OF A MECHANICAL SYSTEM WITH QUADRATIC INTEGRALS, Journal of applied mathematics and mechanics, 61(3), 1997, pp. 363-369
A well-known scheme of topological analysis [1] is extended to the cas
e of three or more integrals which are quadratic functions of the velo
city. The bifurcation set is parametrized by Lagrange multipliers, whi
ch corresponds to a transition to the dual surface. As an example, the
motion of a rigid body in a field with quadratic potential is conside
