## Abstract The subject presented in this paper concerns the approximation of the eddy current problem in nonβstationary geometries with sliding interfaces. The physical system is supposed to be composed of two solid parts: a fixed one (stator) and a moving one (rotor) which slides in contact with
In this paper, two mortar versions of the so-called projection nonconforming and the mixed element methods are proposed, respectively, for nonselfadjoint and indefinite second-order elliptic problems. It is proven that the mortar mixed element method is equivalent to the mortar projection nonconform
