Stability of the inverse boundary value problem for the biharmonic operator : Logarithmic estimates.

In this article, we establish logarithmic stability estimates for the determination of the perturbation of the biharmonic operator from partial data measurements when the inaccessible part of the domain is flat and homogeneous boundary conditions are assumed on this part. This ia an improvement to a log-log type stability estimate prved earlier for the partial data case.
