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…

On the renormalization of Coulomb interactions in two-dimensional tilted Dirac fermions
Yu-Wen Lee, Yu-Li Lee
We investigate the effects of long-ranged Coulomb interactions in a tilted Dirac semimetal in two dimensions by using the perturbative renormalization-group method. Depending on th…
