Global existence of solutions to Keller-Segel chemotaxis system with heterogeneous logistic source and nonlinear secretion

Gurusamy Arumugam, Asha K. Dond, André H. Erhardt

摘要:

我们研究了具有逻辑源和非线性分泌的Keller-Segel趋化系统:\begin{align*} u_t=Δu- \nabla\cdot(u\nabla v)+κ(|x|)u-μ(|x|)u^p\quad\text{and}\quad 0=Δv-v+u^γ, \end{align*},其中$κ(\cdot),~μ(\cdot):[0,R]\rightarrow [0,\infty)$,$γ\in (1,\infty)$,$p\in(γ+1,\infty)$和$Ω\subset \mathbb{R}^n, n\geq 2$ .在适当的初始条件和函数$κ(\cdot)$和$μ(\cdot).$的假设下,我们证明了该系统解的整体存在性

英文摘要:

We study the following Keller-Segel chemotaxis system with logistic source and nonlinear secretion: \begin{align*} u_t=Δu- \nabla\cdot(u\nabla v)+κ(|x|)u-μ(|x|)u^p\quad\text{and}\quad 0=Δv-v+u^γ, \end{align*} where $κ(\cdot),~μ(\cdot):[0,R]\rightarrow [0,\infty)$, $γ\in (1,\infty)$, $p\in(γ+1,\infty)$ and $Ω\subset \mathbb{R}^n, n\geq 2$. For this system, we prove the global existence of solutions under suitable assumptions on the initial condition and the functions $κ(\cdot)$ and $μ(\cdot).$
