A gauge-invariant unique continuation criterion for waves in asymptotically Anti-de Sitter spacetimes

Athanasios Chatzikaleas, Arick Shao

We reconsider the unique continuation property for a general class of tensorial Klein-Gordon equations of the form \begin{align*} \Box_{g} ϕ+ σϕ= \mathcal{G}(ϕ,\nabla ϕ) \text{,} \…
