An Explicit Logistic Damping Criterion for Boundedness in a Fully Parabolic Keller--Segel System
Jie Jiang
We study the fully parabolic Keller--Segel system \[ u_t=Δu-χ\nabla\!\cdot(u\nabla v)+λu-μu^2, \qquad τv_t=Δv-v+u \] in a bounded smooth convex domain. For every fixed , we pr…

On a Keller--Segel System with Density-Suppressed Motility, Indirect Signal Production, and External Sources
Yujiao Sun, Jie Jiang
This paper investigates an initial-Neumann boundary value problem for a Keller--Segel system with parabolic-parabolic-ODE coupling. The model incorporates a signal-dependent, non-i…
