Numerical Construction of Quasi-Periodic Solutions for Nonlinear PDEs: I. Bounded Perturbation
Mingwei Fu, Bin Shi
In this paper, we propose an alternating numerical scheme for constructing quasi-periodic solutions to a class of nonlinear partial differential equations (PDEs) with bounded pertu…

Numerical Construction of Quasi-Periodic Solutions Beyond Symplectic Integrators
Mingwei Fu, Bin Shi
Symplectic integrators are the established standard for long-term simulations of nearly-integrable Hamiltonian systems due to their preservation of geometric structures. However, t…
