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.

New solutions of equations on $\mathbb {R}^n$
We consider some weakly nonlinear elliptic equations on the whole space and use local and global bifurcations methods to construct solutions periodic in one variable and decaying in the otherExpand

Semilinear Neumann boundary value problems on a rectangle
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 ofExpand
