Existence and Instability of Traveling Pulses of Keller-Segel System with Nonlinear Chemical Gradients and Small Diffusions
Chueh-Hsin Chang, Yu-Shuo Chen, John M. Hong +1
In this paper, we consider a generalized model of Keller-Segel system with nonlinear chemical gradient and small cell diffusion. The existence of the traveling pulses f…

Long-time asymptotic solution structure of Camassa-Holm equation subject to an initial condition with non-zero reflection coefficient of the scattering data
Chueh-Hsin Chang, Ching-Hao Yu, Tony Wen-Hann Sheu
In this article we numerically revisit the long-time solution behavior of the Camassa-Holm equation. The finite difference solution of this integrable equation is sought subject to…
