Two-scale convergence in thin domains with locally periodic rapidly oscillating boundary

Original · EN

The aim of this paper is to adapt the notion of two-scale convergence in Lᵖ to the case of a measure converging to a singular one. We present a specific case when a thin cylinder with locally periodic rapidly oscillating boundary shrinks to a segment, and the corresponding measure charging the cylinder converges to a one-dimensional Lebegues measure of an interval. The method is then applied to the asymptotic analysis of linear elliptic operators with locally periodic coefficients in a thin cylinder with locally periodic rapidly varying thickness.
