Título/Tópico:
On a family of gradient type projection methods for nonlinear ill-posed problems

Resumo: 
We propose and analyze a family of successive projection methods whose step direction is the same as Landweber method for solving nonlinear ill-posed problems that satisfy the Tangential Cone Condition (TCC). This family encompasses Landweber method, the minimal error method, and the steepest descent method; thus providing an unified framework for the analysis of these methods. Moreover, we define in this family new methods which are convergent for the constant of the TCC in a range twice as large as the one required for the Landweber and other gradient type methods.
