Long-time asymptotics for a complex cubic Camassa-Holm equation
Hongyi Zhang, Yufeng Zhang, Binlu Feng
In this paper, we investigate the Cauchy problem of the following complex cubic Camassa-Holm (ccCH) equation $$m_{t}=b u_{x}+\frac{1}{2}\left[m\left(|u|^{2}-\left|u_{x}\right|^{2}\…

A class of extended high-dimensional nonisospectral KdV hierarchies and symmetry
Haifeng Wang, Yufeng Zhang, Binlu Feng
We construct a new class of N-dimensional Lie algebras and apply them to integrable systems. In this paper, we obtain a nonisospectral KdV integrable hierarchy by introducing a non…
