摘要

In this note, we correct the proofs for the error estimates of the time differences in a Robin-Robin coupling method for a parabolic-parabolic interface problem, as proposed and analyzed in Burman et al. (Numer. Algorithms, 99, 921-948, 2025). These estimates remain higher order convergent under suitable additional assumptions.
