摘要:

研究了一个生物网络形成模型的强解的可能爆破性。Cai和D.胡\cite{HC}。该模型表示为一个三次非线性椭圆抛物方程组的初边值问题。我们得到了一个关于强解可能爆破时间的代数方程。该方程给出了各种给定数据如何有助于解的爆破的信息。作为一个副产品,我们的发展,我们建立了一个$W^{1,q}$估计的解决方案的椭圆型方程,显示了明确的依赖于椭圆系数的上界。

英文摘要:

We investigate the possible blow-up of strong solutions to a biological network formation model originally introduced by D. Cai and D. Hu \cite{HC}. The model is represented by an initial boundary value problem for an elliptic-parabolic system with cubic non linearity. We obtain an algebraic equation for the possible blow-up time of strong solutions. The equation yields information on how various given data may contribute to the blow-up of solutions. As a by-product of our development, we establish a $W^{1,q}$ estimate for solutions to an elliptic equation which shows the explicit dependence of the upper bound on the elliptic coefficients.
