Recent Progress on Nonlinear Schrödinger Systems with Quadratic Interactions
Recent Progress on Nonlinear Schrödinger Systems with Quadratic Interactions
The study of nonlinear Schrödinger systems with quadratic interactions has attracted much attention in the recent years. In this paper, we summarize time decay estimates of small solutions to the systems under the mass resonance condition in 2-dimensional space. We show the existence of wave operators and modified wave operators …
