偏微分方程分析 2024-08-28 v3

摘要

我们考虑具有实的、可测的、时间依赖系数的二阶退化抛物方程。我们允许由空间 A2A_2-权决定的退化椭圆性。我们证明了基本解的存在性并推导了高斯估计。我们的构造基于 Kato 的原创工作 \cite{Kato}。

备注

In this version, we have added more details in Section 3 of the paper. Section 3 contains the proof of the uniqueness part of our main result and as the argument uses Steklov averages and contains some subtleties, we now supply the full detail
