             ``局所化された Dirichlet to Neumann map による導電係数の
               有限階微分係数の同定''


＜研究発表要旨＞
 We consider the problem of determining conductivity and its derivatives 
of an isotropic, static conductive medium  from the measurements of the 
electric potential on the boundary and the corresponding current flux 
across the boundary, that is, from the Dirichlet to Neumann map, under 
some regularity assumption on the conductivity and the boundary.We give 
an explicit reconstruction formula by using some localized Dirichlet data.
