Stability and instability for the fully parabolic Keller-Segel system around constant equilibrium

Jaewook Ahn, Jae-Myoung Kim, Junha Kim

This paper studies the Cauchy problem for the fully parabolic Keller-Segel system. The main results show that there exists a critical threshold $A_{crit} > 0$ for steady states $…

Keller-Segel-Navier-Stokes systems involving general sensitivities with Signal-Dependent Power-Law Decay

Jaewook Ahn, Sukjung Hwang

This paper investigates a two-dimensional Keller--Segel--Navier--Stokes system with a tensor-valued chemotactic sensitivity $S (x, n, c)$ . Under a signal-dependent power-decay conditi…
