B. Canuto et al., Quantitative estimates of unique continuation for parabolic equations and inverse initial-boundary value problems with unknown boundaries, T AM MATH S, 354(2), 2001, pp. 491-535
In this paper we obtain quantitative estimates of strong unique continuatio
n for solutions to parabolic equations. We apply these results to prove sta
bility estimates of logarithmic type for an inverse problem consisting in t
he determination of unknown portions of the boundary of a domain Omega in R
-n, from the knowledge of overdetermined boundary data for parabolic bounda
ry value problems.
