  • Psi-series of quadratic vector fields on the plane 

    Delshams Valdés, Amadeu; Mir, Arnau (1997)
    Article
    Open Access
    Psi-series (i.e., logarithmic series) for the solutions of quadratic vector fields on the plane are considered. Its existence and convergence is studied, and an algorithm for the location of logarithmic singularities is ...
  • Psi-series, singularities of solutions and integrability of polynomial systems 

    Mir, Arnau; Delshams Valdés, Amadeu (1996)
    Article
    Open Access
    Psi-series (i.e., logarithmic series) of $m$-dimensional polynomial systems are considered. Its existence and convergence is studied, and an algorithm of location of logarithmic singularities is developed. Moreover, ...
