      Palacián Subiela, Jesús Francisco Upna Orcid; Vidal Díaz, Claudio; Vidarte, Jhon; Yanguas Sayas, Patricia Upna Orcid (IOP Publishing, 2019)   Artículo / Artikulua  OpenAccess
      A family of perturbed Hamiltonians H = 1/2 (x^2 + X^2) − 1/2 (y^2 + Y^2)+1/2 (z^2 + Z^2) + 2[ (x^4 + y^4 + z^4) + (x^2 y^2 + x^2 z^2 + y^2 z^2)] in 1: −1:1 resonance depending on two real parameters is considered. We ...
    • Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential 

      Lanchares, Víctor; Pascual, Ana Isabel; Iñarrea, Manuel; Salas, José Pablo; Palacián Subiela, Jesús Francisco Upna Orcid; Yanguas Sayas, Patricia Upna Orcid (Springer, 2019)   Artículo / Artikulua  OpenAccess
      We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon– Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced system with at most four non degenerate ...

    • Singular reduction of resonant Hamiltonians 

      Meyer, Kenneth Ray; Palacián Subiela, Jesús Francisco Upna Orcid; Yanguas Sayas, Patricia Upna Orcid (IOP PublishingLondon Mathematical Society, 2018)   Artículo / Artikulua  OpenAccess
      We investigate the dynamics of resonant Hamiltonians with n degrees of freedom to which we attach a small perturbation. Our study is based on the geometric interpretation of singular reduction theory. The flow of the ...
