Asymptotic Analysis of Laplacian Operator in Thin Domains on the Sphere with Highly Oscillatory Boundary

Abstract

In this work we analyse the convergence of solutions of the Poisson equation with Neumann boundary conditions in a thin domain with highly oscillatory behavior ${\mathcal{U}}^{\epsilon }$ contained in the sphere ${\mathbb{S}}^2$. Using the Multiple Scales method, we obtain the homogenized limit problem and analyse the convergence of solutions, as $\epsilon$ tends to $0$. Introducing appropriate correctors, we show strong convergence and give error estimates.
