             ``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.
