半线性超耗散heat equation的Cauchy问题

On the Cauchy problem for a semi-linear hyperdissipative heat equation

Franka Baaske, Romaric Kana Nguedia

摘要:

在Besov空间和Triebel-Lizorkin空间中研究了一类半线性超耗散热方程的Cauchy问题,该问题通过Duhamel原理与广义Gauss-Weierstrass半群相联系.利用半群的热光滑性质,证明了在时间上局部的弱解和强解的存在唯一性。此外,我们还研究了问题的适定性。

英文摘要:

The paper is concerned with the Cauchy problem for a semi-linear hyperdissipative heat equation in Besov and Triebel-Lizorkin spaces which is related to the generalized Gauss-Weierstrass semi-group via Duhamel's principle. Using caloric smoothing properties of the semi-group we prove existence and uniqueness of mild and strong solutions which are local in time. Moreover, we study well-posedness of the problem.
