A novel efficient structure-preserving exponential integrator for Hamiltonian systems
Pan Zhang, Fengyang Xiao, Lu Li
We propose a linearly implicit structure-preserving numerical method for semilinear Hamiltonian systems with polynomial nonlinearities, combining Kahan's method and exponential int…

On the steadiness of symmetric solutions to higher order perturbations of KdV
Long Pei, Fengyang Xiao, Pan Zhang
We consider the traveling structure of symmetric solutions to the Rosenau-Kawahara-RLW equation and the perturbed R-KdV-RLW equation. Both equations are higher order perturbations…
