78 p, 604.1 KB KAM theory for conformally symplectic systems / Calleja, Renato C. ; Celletti, A. (Alessandra) ; Llave, Rafael de la ; Universitat Autònoma de Barcelona. Centre de Recerca Matemàtica
We present a KAM theory for some dissipative systems (geometrically, these are conformally symplectic systems, i. e. systems that transform a symplectic form into a multiple of itself). For systems with n degrees of freedom depending on n parameters we show that it is possible to find solutions with n-dimensional (Diophantine) frequencies by adjusting the parameters. [...]

82 p, 3.8 MB Fast numerical algorithms for the computation of invariant tori in Hamiltonian systems / Huguet, Gemma ; Llave, Rafael de la ; Sire, Yannik ; Universitat Autònoma de Barcelona. Centre de Recerca Matemàtica
In this paper, we develop numerical algorithms that use small requirements of storage and operations for the computation of invariant tori in Hamiltonian systems (exact symplectic maps and Hamiltonian vector fields). [...]
