Threshold scattering for the 2d radial cubic-quintic NLS

Jason Murphy

We consider the cubic-quintic nonlinear Schrödinger equation in two space dimensions. For this model, X. Cheng established scattering for data with mass strictly below that o…

Scattering for the non-radial energy-critical inhomogeneous NLS

Carlos M. Guzmán, Jason Murphy

We prove scattering below the ground state threshold for an energy-critical inhomogeneous nonlinear Schrödinger equation in three space dimensions. In particular, we extend results…

Failure of scattering to solitary waves for long-range nonlinear Schrödinger equations

Jason Murphy, Kenji Nakanishi

We consider nonlinear Schrödinger equations with either power-type or Hartree nonlinearity in the presence of an external potential. We show that for long-range nonlinearities, sol…

Scattering below the ground state for the 2 radial nonlinear Schrödinger equation

Anudeep Kumar Arora, Benjamin Dodson, Jason Murphy

We revisit the problem of scattering below the ground state threshold for the mass-supercritical focusing nonlinear Schrödinger equation in two space dimensions. We present a simpl…

Numerical simulations for the energy-supercritical nonlinear wave equation

Jason Murphy, Yanzhi Zhang

We carry out numerical simulations of the defocusing energy-supercritical nonlinear wave equation for a range of spherically-symmetric initial conditions. We demonstrate numericall…

Scattering for defocusing energy subcritical nonlinear wave equations

Benjamin Dodson, Andrew Lawrie, Dana Mendelson +1

We consider the Cauchy problem for the defocusing power type nonlinear wave equation in -dimensions for energy subcritical powers in the range . We prove that…
