Splitting of separatrices for (fast) quasiperiodic forcing
Delshams Valdés, Amadeu; Gelfreich, Vassili; Jorba, Angel; Martínez-Seara Alonso, M. Teresa (1996)
Article
Accés obertWe consider fast quasiperiodic perturbations of a pendulum with two frequencies $(1,\gamma)$, where $\gamma$ is the golden mean number. For small perturbations such that its Fourier coefficients (the ones associated to ... -
Stability and asymptotic behaviour of the vertical family of periodic orbits around L_5 of the restricted three-body problem
Jorba, Angel; Villanueva Castelltort, Jordi (1997)
Article
Accés obertIn this work we study some numerical results about a family of periodic orbits of the Restricted Three Body Problem (RTBP). The family considered is one of the Lyapunov families related to the equlibrium point $L_5$. More ... -
Teoria Kam Sin Coordenadas Accion-Angulo
González, Alejandra; Jorba, Angel; Llave Canosa, Rafael de la; Villanueva Castelltort, Jordi (2001)
Article
Accés obertThe classical KAM methods, strongly supported on the use of canonical trans- formations in the action-angle context, are not effcient to be applied to a wide range of systems in which the Hamiltonian is known (for instance) ... -
The fine geometry of the Cantor families of invariant tori in hamiltonian systems
Jorba, Angel; Villanueva Castelltort, Jordi (2000)
Article
Accés obertThis work focuses on the dynamics around a partially elliptic, lower dimensional torus of a real analytic Hamiltonian system. More concretely, we investigate the abundance of invariant tori in the directions of the phase ... -
Unstable manifolds computation for the 2-D plane Poiseuille flow
Sánchez Casas, José Pablo; Jorba, Angel (2003)
Article
Accés obertWe follow the unstable manifold of periodic and quasi-periodic solutions for the Poiseuille problem, using two formulations: holding constant flux or mean pressure gradient. By means of a numerical integrator of the ... -
Unstable manifolds computation for the two-dimensional plane Poiseuille flow
Sánchez Casas, José Pablo; Jorba, Angel (2003)
Article
Accés obertIn this work we study some aspects of the dynamics of the plane Poiseuille problem in dimension 2, in what refers to the connection among different configurations of the flow. The fluid is confined in a channel of plane ... -
