具有尺度不变阻尼和时间导数非线性的弱耦合wave equations方程的新爆破结果

New blow-up result for the weakly coupled wave equations with a scale-invariant damping and time derivative nonlinearity

Makram Hamouda, Mohamed Ali Hamza

摘要:

本文考虑了\textit{scale-invariant case}中的弱耦合波动方程组,该方程组具有时间导数非线性项。在通常的小初始数据的假设下,我们通过获得一个新的候选临界曲线,得到了一个改进的爆破区域的界定。更确切地说,我们提高了在\cite{Palmieri}中得到的结果,在本工作中考虑的系统。我们相信我们的结果是最优的,在这个意义上,在这里得到的爆破区域之外,我们可以推测解的整体存在性。

英文摘要:

We consider in this article the weakly coupled system of wave equations in the \textit{scale-invariant case} and with time-derivative nonlinearities. Under the usual assumption of small initial data, we obtain an improvement of the delimitation of the blow-up region by obtaining a new candidate for the critical curve. More precisely, we enhance the results obtained in \cite{Palmieri} for the system under consideration in the present work. We believe that our result is optimal in the sense that beyond the blow-up region obtained here we may conjecture the global existence of the solution.
