算子矩阵生成半群的渐近性

Asymptotics of semigroups generated by operator matrices

Delio Mugnolo

摘要:

本文综述了关于算子矩阵生成的算子半群的一些已知结果。这些抽象的结果被应用到域或度量图上的一类具有动态边界条件的发展方程的适定性/不适定性。特别是,我们的不适定性结果的热方程与一般Wentzell型边界条件的补充,以前得到的,除其他外,Bandle-von Below-Reichel和Vitillaro-Vázquez。

英文摘要:

We survey some known results about operator semigroup generated by operator matrices with diagonal or coupled domain. These abstract results are applied to the characterization of well-/ill-posedness for a class of evolution equations with dynamic boundary conditions on domains or metric graphs. In particular, our ill-posedness results on the heat equation with general Wentzell-type boundary conditions complement those previously obtained by, among others, Bandle-von Below-Reichel and Vitillaro-Vázquez.
