On the effectiveness of spectral methods for the numerical solution of multi-frequency highly-oscillatory Hamiltonian problems
Multi-frequency, highly-oscillatory Hamiltonian problems derive from the
mathematical modelling of many real life applications. We here propose a
variant of Hamiltonian Boundary Value Methods (HBVMs), which is able to
efficiently deal with the numerical solution of such problems.Comment: 28 pages, 4 figures (a few typos fixed
