报告摘要: This talk is concerned with the inverse problem of determining three spatially varying functions including the source term and the mass density for a curved plate. The stability of determining these parameters is derived by the classical Carleman estimates and observability inequalities. Moreover, by developing a geometrical multiplier identity and using the compactness-uniqueness method, the tangential derivative can be removed. Two kinds of boundary conditions are considered: one is the hinged boundary conditions and the other is the clamped boundary conditions. In particular, the case of the Euler-Bernoulli plate is included.
