On stability of equilibrium of nonholonomic systems : PMM vol. 39, n 6, 1975, pp. 1135–1140

The problem of stability of motion of nonholonomic systems was first considered by Whittaker in [1], and developed in [2–7] et al. The most general results in investigating the stability of equilibrium of conservative nonholonomic systems and in clarifying the influence of the dissipative forces on this stability, were obtained in [5]. In the present paper we give a further generalization of the results obtained in [5].
