具有$p$ -结构的非线性抛物型方程组的时空离散

Space-time discretization for nonlinear parabolic systems with $p$-structure

Luigi C. Berselli, Michael Růžička

摘要:

本文考虑具有椭圆部分的非线性抛物型方程组,该方程组也可以退化。我们证明了足够光滑的解决方案的最佳误差估计。主要的新颖性,相对于以前的结果,是我们得到的估计直接不引入中间半离散问题。此外,我们证明了连续问题的解的存在性所要求的正则性,如果该问题的数据是足够光滑的。

英文摘要:

In this paper we consider nonlinear parabolic systems with elliptic part which can be also degenerate. We prove optimal error estimates for smooth enough solutions. The main novelty, with respect to previous results, is that we obtain the estimates directlywithout introducing intermediate semi-discrete problems. In addition, we prove the existence of solutions of the continuous problem with the requested regularity, if the data of the problem are smooth enough.
