本文研究了具有体积填充效应的趋化模型在齐次Neumann边界条件下解的渐近性态。建立了一个非光滑形式的eojasiewicz-Simon不等式,证明了当时间趋于无穷大时,系统的解收敛于W1,p(Ω)× W1,p(Ω),p> max(n,2),Ω <$Rn中的平衡点.我们还得到了一个估计的衰减率平衡。
In this paper, we study the asymptotic behavior of solutions to a chemotaxis model with volume-filling effect subject to the homogeneous Neumann boundary conditions. We establish a non-smooth version of eojasiewicz-Simon inequality, and we prove that as time goes to infinity the solution to our system converges to an equilibrium in W 1,p (Ω) × W 1,p (Ω), p> max(n ,2 ),Ω ⊂ R n . We also obtain an estimate of the decay rate to equilibrium.
