Scattering for the quadratic nonlinear Schrödinger system in ${\mathbb{R}}^5$ without mass-resonance condition

Masaru Hamano, Takahisa Inui, Kuranosuke Nishimura

We consider the quadratic nonlinear Schrödinger system (NLS system) \begin{align*}\begin{cases} i\partial_t u + Δu = v \overline{u}, \\ i\partial_t v+κΔv = u^2, \end{cases} \text{…
