间断系数抛物型算子基本解的估计

Estimate of the Fundamental Solution for Parabolic Operators with Discontinuous Coefficients

Michele Di Cristo, Kyoungsun Kim, Gen Nakamura

摘要:

我们将证明,对于系数足够光滑的标量抛物型方程的基本解,已知的相同类型的估计也适用于系数不连续的散度型标量抛物型方程的基本解关于空间变量的一阶导数。该估计对于许多应用非常重要。例如,对于从边界测量识别导热介质内部的夹杂物的反问题,这是重要的。

英文摘要:

We will show that the same type of estimates known for the fundamental solutions for scalar parabolic equations with smooth enough coefficients hold for the first order derivatives of fundamental solution with respect to space variables of scalar parabolic equations of divergence form with discontinuous coefficients. The estimate is very important for many applications. For example, it is important for the inverse problem identifying inclusions inside a heat conductive medium from boundary measurements.
