Abstract

Sufficient conditions are given for an implicit function theorem to hold. The result is established by an application of the Dynamical Systems Method (DSM). It allows one to solve a class of nonlinear operator equations in the case when the Fr´echet derivative of the nonlinear operator is a smoothing operator, so that its inverse is an unbounded operator.
