The Levenberg-Marquardt Iteration for Numerical Inversion of the Power Density Operator
Guillaume Bal, Wolf Naetar, Otmar Scherzer +1
In this paper we develop a convergence analysis in an infinite dimensional setting of the Levenberg-Marquardt iteration for the solution of a hybrid conductivity imaging problem. T…
