Semilinear damped wave equations with data from Sobolev spaces of negative order: the critical case in Euclidean setting and in the Heisenberg space

M D'Abbicco - arXiv preprint arXiv:2408.11756, 2024 - arxiv.org
In this note, we prove the global existence of solutions to the semilinear damped wave
equation in $\mathbb {R}^ n $, $ n\leq6 $, with critical nonlinearity under the assumption that …
