On uniqueness for the critical wave equation

Nader Masmoudi, Fabrice Planchon

Research output: Contribution to journalArticlepeer-review


We prove the uniqueness of weak solutions to the critical defocusing wave equation in 3D under a local energy inequality condition. More precisely, we prove the uniqueness of u ∈ Lt(Ḣ 1) ∩ Ẇt1,∞(L2), under the condition that u verifies some local energy inequalities.
