具有奇异热导率的Heat equation

Heat equation with singular thermal conductivity

Michael Ruzhansky, Mohammed Elamine Sebih, Niyaz Tokmagambetov

摘要:

本文研究了具有非规则空间依赖导热系数的热传导方程。我们证明了它在适当的很弱意义下有解。此外,还证明了该解的唯一性,以及当经典解存在时与经典解的一致性.事实上,我们允许系数是一个分布,一个有趣的例子是Delta函数。

英文摘要:

In this paper, we study the heat equation with an irregular spatially dependent thermal conductivity coefficient. We prove that it has a solution in an appropriate very weak sense. Moreover, the uniqueness result and consistency with the classical solution if the latter exists are shown. Indeed, we allow the coefficient to be a distribution with a toy example of a Delta-function.
