Title: Inverse problems of Calderon and Gelfand type with partial data




We discuss the following operator theoretical results on an inverse problem
of Calderon or Gelfand type with partial data for anisotropic Lipschitz conductivities:

(i) The selfadjoint Dirichlet operator associated withan elliptic differential expression
on a bounded Lipschitz domain is determined uniquely up to unitary equivalence by the knowledge
of the Dirichlet-to-Neumann map on an open subset of the boundary,

(ii) the Dirichlet operator can be reconstructed from the residuals of the

Dirichlet-to-Neumann map on this subset.
