  • Exotic Galilean Symmetry and Non-Commutative Mechanics 
    Horváthy, P.A.; Martina, L.; Stichel, P.C. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Some aspects of the ''exotic'' particle, associated with the two-parameter central extension of the planar Galilei group are reviewed. A fundamental property is that it has non-commuting position coordinates. Other and ...
  • Structure Preserving Discretizations of the Liouville Equation and their Numerical Tests 
    Levi, D.; Martina, L.; Winternitz, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    The main purpose of this article is to show how symmetry structures in partial differential equations can be preserved in a discrete world and reflected in difference schemes. Three different structure preserving discretizations ...
