  • Principal part of multi-parameter displacement functions 

    Mardešić, Pavao; Saavedra, Mariana; Uribe, Marco (2012)
    In this paper we investigate planar polynomial multi-parameter deformations of Hamiltonian vector fields. We study first all coefficients in the development of the displacement function on a transversal to the period ...

  • Unfolding of the hamiltonian triangle vector field 

    Mardešić, Pavao; Saavedra, Mariana; Wallace, M.; Uribe, Marco (2011)
    In this paper, we study unfoldings of the Hamiltonian triangle vector field within quadratic vector fields. We complete and correct some previous results of Żołądek
