Construction of a solution for the two-component radial Gross-Pitaevskii system with a large coupling parameter

Jean-Baptiste Casteras, Christos Sourdis

We consider strongly coupled competitive elliptic systems that arise in the study of two-component Bose-Einstein condensates. As the coupling parameter tends to infinity, solutions…

On Helmholtz equations and counterexamples to Strichartz estimates in hyperbolic space

Jean-Baptiste Casteras, Rainer Mandel

In this paper, we study nonlinear Helmholtz equations (NLH) $- Δ_{H^{N}} u - \frac{( N - 1 ) ^{2}}{4} u - λ^{2} u = Γ∣ u ∣^{p - 2} u$ in $H^{N}$ , $N \geq 2$ where $Δ_{H^{N}}$ d…
