Agah D. Garnadi Application of Core Identification to Starshape Constant Conductivity Inclusion (386K, "Postscript") ABSTRACT. The problem of determining the interface separating a constant conductivity inclusion with starshape support from boundary measurement data of a solution of the corresponding PDEs is considered. An equivalent statement as a nonlinear integral equation is obtained. The problem is analyzed and implemented using Fourier method. Numerical experiments based on simplified iteratively regularized Gauss-Newton method (sIRGNM) are presented.
