Iterative Construction of Fixed Points of Contractive Type Mappings in Banach Spaces, nonlinear ordinary and partial differential equations, etc.) can be formulated in terms of finding fixed points of a given nonlinear mapping defined on some subset of an infinite dimensional functional space. For compact mappings a general existence theory of fixed points based upon topological arg
