Iterative tools for locating mounted issues of non-expansive operators in Hilbert areas were defined in lots of guides. during this monograph we strive to offer the tools in a consolidated method. We introduce a number of periods of operators, research their houses, outline iterative tools generated through operators from those periods and current common convergence theorems. in this foundation we speak about the stipulations below which specific tools converge. a wide a part of the consequences provided during this monograph are available in quite a few kinds within the literature (although numerous effects provided listed below are new). we've attempted, even if, to teach that the convergence of a giant classification of new release equipment follows from basic houses of a few periods of operators and from a few normal convergence theorems.
