2月22日(木) 15:30 -- 17:00 Jin Cheng(群馬大学工学部) ``An inverse problem to determine anisotoropic conductivity'' (tentative title) <Abstarct> We discuss the two dimensional inverse problem of determining the anisotropic conductivity from the Dirichlet to Neumann map. The global conformal uniqueness is proved. The key of the proof is the global uniqueness result for the inverse problem of determining the convection terms from the Dirichlet to Neumann map and quasi-conformal mapping.
