A parameterization method for quasi-periodic systems with noise: computation of random invariant tori
Pingyuan Wei, Lei Zhang
This work is devoted to studying normally hyperbolic invariant manifolds (NHIMs) for a class of quasi-periodically forced systems subject to additional stochastic noise. These syst…

Analysis of any order Runge-Kutta Spectral Volume Schemes for 1D Hyperbolic Equations
Ping Wei, Qing-Song Zou
In this paper, we analyze any-order Runge-Kutta spectral volume schemes (RKSV(s,k)) for solving the one-dimensional scalar hyperbolic equation. The RKSV(s,k) was constructed by usi…
