Boundary layers for transmission problems with singularities
Abderrahman Maghnouji, Serge Nicaise · DOAJ (DOAJ: Directory of Open Access Journals) · 2006
We study two-dimensional transmission problems for the Laplace operator for two diffusion coefficients. We describe the boundary layers of this problem and show that the layers appear only in the part where the coefficient is large. The relationship with the singularities of the limit problem is also described.
