Global well-posedness of the energy subcritical nonlinear wave equation with initial data in a critical space

In this paper we prove global well-posedness and scattering for the defocussing, energy -sub critical, nonlinear wave equation on R 1 + 3 with initial data in a critical Besov space. No radial symmetry assumption is needed. (c) 2024 Elsevier Inc. All rights are reserved, including those for text and data mining, AI training, and similar technologies.
