摘要:

本文的主要目标是研究含退化系数的电导率问题在两个刚性导体存在下解的正则性与稳定性,其中一个导体保持静止,另一个导体沿某一方向平移足够小的距离。我们将证明解关于小平移距离是光滑且稳定的。我们的结果涵盖以下三种情形:两个理想导体、两个绝缘体、一个理想导体与一个绝缘体。此外,我们将结果推广到由含部分无穷系数的Lamé系统(拉梅系统)建模的弹性力学问题。

英文摘要:

The main objective of this paper is to study the regularity and stability for solutions to the conductivity problems with degenerate coefficients in the presence of two rigid conductors, as one conductor keeps motionless and another conductor moves in some direction by a sufficiently small translational distance. We will show that the solutions are smooth and stable with respect to the small translational distance. Our results contain the following three cases: two perfect conductors, two insulators, a perfect conductor and an insulator. Further, we extend the results to the elasticity problem modeled by the Lamé system with partially infinite coefficients.
