Abstract In this manuscript, we consider a non-local porous medium equation with non-local diffusion effects given by a fractional heat operator in two space dimensions for Global in time existence of weak solutions is shown by employing a time semi-discretization of the equations, an energy inequality and the Div-Curl lemma.

具有时空非局部达西定律的连续性方程弱解的存在性

摘要 在这篇手稿中,我们考虑了一个具有非局部扩散效应的非局部多孔介质方程,该方程由二维空间维度的分数热算子给出,用于弱解的全局时间存在性通过使用方程的时间半离散化显示,能量不等式和 Div-Curl 引理。
