Abstract
An electrical potential U on a bordered Riemann surface X with conductivity function σ>0 satisfies equation d(σ d c U)=0. The problem of effective reconstruction of σ from electrical currents measurements (Dirichlet-to-Neumann mapping) on the boundary: U| bX ↦ σ d c U| bX is studied. We extend to the case of Riemann surfaces the reconstruction scheme given, firstly, by R. Novikov (Funkc. Anal. Ego Priloz. 22:11–22, 2008) for simply connected X. We apply for this new kernels for \(\bar{ \partial }\) on the affine algebraic Riemann surfaces constructed in Henkin (arXiv:0804.3761, 2008).
