Global Regularity For The Nonlinear Wave Equation With Slightly Supercritical Power
January 1, 2023
We consider the defocusing nonlinear wave equation ❑u D jujp ⠀1u in R3 ⠂ & UOELIG;0; 1/. We prove that for any initial datum with a scaling-subcritical norm bounded by M0 the equation is globally well-posed for p D 5 C i, where i 2 .0; i0.M0//.
