摘要

我们考虑在光滑凸有界域ΩRn\Omega \subset \mathbb{R}^nn2n \geq 2)中,带logistic源f(u):=auμu2f(u) := au-\mu u^2且在非线性诺伊曼边界条件uν=up\frac{\partial u}{ \partial \nu } = |u|^{p}p>1p>1)下趋化系统的经典解。本文旨在证明:若p<32p<\frac{3}{2},且当n=2n=2μ>0\mu >0,或当n3n\geq 3μ\mu充分大,则抛物-椭圆趋化系统存在唯一的、在Ω×(0,)\Omega \times (0, \infty)中有界的正的整体经典解。对于抛物-抛物趋化系统,若p<32p<\frac{3}{2}n=2n=2μ>0\mu>0,或p<75p<\frac{7}{5}n=3n=3μ\mu充分大,类似结论也成立。
