# Increasing stability in a partial data inverse boundary value problem for biharmonic operators

@article{LIU2019IncreasingSI, title={Increasing stability in a partial data inverse boundary value problem for biharmonic operators}, author={BOYA LIU}, journal={arXiv: Analysis of PDEs}, year={2019} }

We study the inverse boundary value problems of determining a potential in the Helmholtz type equation for the perturbed biharmonic operator from the knowledge of the partial Cauchy data set. Our geometric setting is that of a domain whose inaccessible portion of the boundary is contained in a hyperplane, and we are given the Cauchy data set on the complement. The uniqueness and logarithmic stability for this problem were established in [34] and [7], respectively. We show, under mild regularity…
