Reducibility of relativistic Schrödinger equation with unbounded perturbations
Yingte Sun, Jing Li
In this paper, we prove a reducibility result for a relativistic Schrödinger equation on torus with time quasi-periodic unbounded perturbations of order 1/2, and finally conjugate…

Reducibility for wave equations of finitely smooth potential with periodic boundary conditions
Jing Li, Yingte Sun, Bing Xie
In the present paper, the reducibility is derived for the wave equations with finitely smooth and time-quasi-periodic potential subjects to periodic boundary conditions. More exact…

Quasi-periodic solution of quasi-linear fifth-order KdV equation
Yingte Sun, Xiaoping Yuan
In this paper, we prove the existence of quasi-periodic small-amplitude solutions for quasi-linear Hamiltonian perturbation of the fifth-order KdV equation on the torus in presence…
