We are interested in the positive doubly periodic solutions, which are even in each variable, of a stationary nonlinear Schrödinger equation in ℝ2, with a small parameter. For any pair of periods (2a, 2b), we construct a branch of solutions that concentrate uniformly to the ground-state solution of the equation.

We consider a semilinear elliptic equation Δu + λf(u) = 0, x ∈ Ω, ∂u/∂n = 0, x ∈ ∂Ω, where Ω is a rectangle (0, a) x (0, b) in R 2 . For balanced and unbalanced f, we obtain partial descriptions of…
