Query: H{\"o}lder stability in determining the potential and the damping
  coefficient in a wave equation   We improve the preceding results obtained by the first and the second authors
in [3]. They concern the stability issue of the inverse problem that consists
in determining the potential and the damping coefficient in a wave equation
from an initial-to-boundary operator. We partially modify the arguments in [3]
to show that actually we have H{\"o}lder stability instead of logarithmic
stability.
