The authors consider a proximal type algorithm for solving the inclusion \(0\in Tx\), where \(T:E\to 2^{E^*}\) is a maximal monotone operator acting in an uniformly convex and smooth real Banach space \(E\). They first prove that the sequence generated by the algorithm is well-defined and then that a necessary and sufficient condition in order for a zero to exist for the inclusion \(0\in Tx\) is the boundedness of that sequence. Finally, they apply the result in the study of a convex minimization problem.
