Research output: Contribution to journalArticlepeer-review


We investigate the initial value problem for a defocusing nonlinear Schrödinger equation with exponential nonlinearity i∂tu + Δu = u(e4π u 2 - 1) in ℝt × ℝx 2. We identify subcritical, critical, and supercritical regimes in the energy space. We establish global well-posedness in the subcritical and critical regimes. Well-posedness fails to hold in the supercritical case.
