二阶elliptic differential operators双层位势的正则化性质

Regularizing properties of the double layer potential of second order elliptic differential operators

Francesco Dondi, Massimo Lanza de Cristoforis

摘要:

利用Schauder空间中双层位势自身切向导数的显式公式,证明了与{ \em非齐次}二阶常系数椭圆型微分算子基本解相关的双层位势的正则化性质的有效性.我们还介绍了特设规范的内核的积分算子,以证明连续性结果的积分算子后的变化的内核,我们适用于层潜力。

英文摘要:

We prove the validity of regularizing properties of a double layer potential associated to the fundamental solution of a {\em nonhomogeneous} second order elliptic differential operator with constant coefficients in Schauder spaces by exploiting an explicit formula for the tangential derivatives of the double layer potential itself. We also introduce ad hoc norms for kernels of integral operators in order to prove continuity results of integral operators upon variation of the kernel, which we apply to layer potentials.
