This paper considers the inverse problem of determining two spatially varying coefficients in the two-dimensional Boussinesq system from observed data of velocity vector and temperature in a given subboundary. Using Carleman estimates, a Lipschitz stability result is proven.
In this paper, we consider the inverse problem of determining two spatially varying coefficients appearing in the two-dimensional Boussinesq sys-tem from observed data of velocity vector and the temperature in a given arbitrarily subboundary. Based on Carleman estimates, we prove a Lipschitz stability result.
