  1. 6. Analysis of the phase space, asymptotic behavior and stability for heavy symmetric top and tippe top

    Författare :Markus Sköldstam; Stefan Rauch-Wojciechowski; Torkel Glad; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symmetric top; tippe top; vertical rotation; truncated sphere; asymptotic trajectories; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis we analyze the phase of the heavy symmetric top and the tippe top. These tops are two examples of physical systems for which the usefulness of integrals of motion and invariant manifolds, in phase space picture analysis, can be illustratedIn the case of the heavy symmetric top, simplified proofs of stability of the vertical rotation have been perpetuated by successive textbooks during the last century.
