Global solvability and boundedness to a attraction–repulsion model with logistic source

open access: yesBoundary Value Problems
In this paper, we deal with an attraction–repulsion model with a logistic source as follows: { u t = Δ u − χ ∇ ⋅ ( u ∇ v ) + ξ ∇ ⋅ ( u ∇ w ) + μ u q ( 1 − u ) in  Q , v t = Δ v − α 1 v + β 1 u in  Q , w t = Δ w − α 2 w + β 2 u in  Q , $$\begin{aligned ...

Analyzing the Solution of Chemotaxis Equations with Logistic Source Term [PDF]

open access: yesMathematical Problems in Engineering, 2021
When the parameters have the characteristics of sensitivity and specificity, while the traditional analysis method is the analysis of equations, under the influence of the characteristics of parameters, because the ability to consider the overall existence and limitations of the equation is weak, this leads to the deviation of the analysis results ...

Existence of global solutions to chemotaxis fluid system with logistic source

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We establish the existence of global solutions and $L^q$ time-decay of a three dimensional chemotaxis system with chemoattractant and repellent. We show the existence of global solutions by the energy method.
