We establish uniqueness results by the Carleman estimate. A Lame system with variable coefficients has different principal parts and usual application of the Carleman estimate is difficult, and for the proof of the uniqueness, we reduce the Lame system to a system with the same principal part by introducing a divergence component.departmental bulletin paperGraduate School of Mathematical Sciences, The University of Tokyo1998application/pdfJournal of mathematical sciences, the University of Tokyo45627692AA1102165313405705https://repository.dl.itc.u-tokyo.ac.jp/record/40266/files/jms050402.pdfeng
