Correction to “The unique continuation property for second order evolution PDEs” [Partial Differ. Equ. Appl. 2, 67 (2021), 46 p] with additional comments
摘要
The proof of the final-time observability inequality in Choulli (Partial Differ Equ.Appl 2:67, 2021, Theorem 5.4) is based on inequality (5.16) (Choulli in Partial Differ Equ Appl 2:67, 2021, proof of Theorem 5.4). The proof of this inequality is unfortunately incorrect. We propose a new proof of Choulli (Partial Differ Equ Appl 2:67, 2021, Theorem 5.4) using another method. We also provide some additional comments.
