In recent years there has been a surge of profound new developments in various aspects of analysis whose connecting thread is the use of Banach space methods. I

Regularization methods aimed at finding stable approximate solutions are a necessary tool to tackle inverse and ill-posed problems. Inverse problems arise in a

The contents of this monograph fall within the general area of nonlinear functional analysis and applications. We focus on an important topic within this area:
