  2. 1. Newton systems of cofactor type in Euclidean and Riemannian spaces

    Author : Hans Lundmark; Franco Magri; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We study second order ordinary differential equations of Newton type with integrals of motion that depend quadratically on the velocity. In particular, we introduce the class of cofactor pair systems, which admit two quadratic integrals of motion of a special form. READ MORE

  4. 2. Contributions to the theory of peaked solitons

    Author : Marcus Kardell; Hans Lundmark; Helge Holden; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this work is to present some new contributions to the theory of peaked solitons. The thesis contains two papers, named "Lie symmetry analysis of the Novikov and Geng-Xue equations, and new peakon-like unbounded solutions to the Camassa-Holm, Degasperis-Procesi and Novikov equations'' and "Peakon-antipeakon solutions of the Novikov equation'' respectively.

  6. 4. Analysis of Dynamics of the Tippe Top

    Author : Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Tippe Top is a toy that has the form of a truncated sphere with a small peg. When spun on its spherical part on a flat supporting surface it will start to turn upside down to spin on its peg. READ MORE

  7. 5. Study of equations for Tippe Top and related rigid bodies

    Author : Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : The Tippe Top consist of a small truncated sphere with a peg as a handle. When it is spun fast enough on its spherical part it starts to turn upside down and ends up spinning on the peg. READ MORE
