Abstract
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 Lam\'{e} system with partially infinite coefficients.
