Abstract

A new continuous regularized Gauss-Newton-type method with simultaneous updates of the operator (F\pr(x(t))F(x(t))+\ep(t)I)1(F^{\pr*}(x(t))F'(x(t))+\ep(t) I)^{-1} for solving nonlinear ill-posed equations in a Hilbert space is proposed. A convergence theorem is proved. An attractive and novel feature of the proposed method is the absence of the assumptions about the location of the spectrum of the operator F(x)F'(x). The absence of such assumptions is made possible by a source-type condition.
