摘要: We consider a class of singularly perturbed equations in planar domains: as the singular perturbation parameter tends to zero, we exhibit a family of solutions concentrating at the boundary with asymptotically periodic profile. As solutions with uniform profile at the boundary were known to exist, the result here reflects the phenomenon of Turing's instability, which triggers formation of inhomogeneous structures from more homogeneous ones.
