  text: We show that solutions to the Ablowitz–Ladik system converge to solutions
    of the cubic nonlinear Schrödinger equation for merely L2 initial data. Furthermore,
    we consider initial data for this lattice model that excites Fourier modes near
    both critical points of the discrete dispersion relation and demonstrate convergence
    to a decoupled system of nonlinear Schrödinger equations.

  text: "We construct solutions with prescribed scattering state to the cubic-quintic
    NLS (mathematical formular)in three spatial dimensions in the class of solutions
    with (mathematical formular). This models disturbances in an infinite expanse
    of (quantum) fluid in its quiescent state— the limiting modulus c corresponds
    to a local minimum in the energy density.\r\nOur arguments build on work of Gustafson,
    Nakanishi, and Tsai on the (defocusing) Gross–Pitaevskii equation. The presence
    of an energy-critical nonlinearity and changes in the geometry of the energy\r\nfunctional
    add several new complexities. One new ingredient in our argument is a demonstration
    that\r\nsolutions of such (perturbed) energy-critical equations exhibit continuous
    dependence on the initial data\r\nwith respect to the weak topology on H1/x."

  text: We consider the Gross–Pitaevskii equation on R^4 and the cubic-quintic nonlinear
    Schrödinger equation (NLS) on R^3 with non-vanishing boundary conditions at spatial
    infinity. By viewing these equations as perturbations to the energy-critical NLS,
    we prove that they are globally well-posed in their energy spaces. In particular,
    we prove unconditional uniqueness in the energy spaces for these equations.
