Abstract: | The complete solutions of the upright and oblique permanent rotations of a symmetric heavy gyroscope with perfect dissipation
are given. The asymptotic stability criteria and unstability criteria for these rotations in the sense of Liapunov and the
sense of Movchan are also given on the basis of exact nonlinear motion equations respectively. The related oblique rotations
are non-isolated. The main subdomains of the regions of asymptotic stability are obtained. The related bifurcation phenomena
are discussed in detail.
