The book offers new techniques for renorming problems, all of them based on a network analysis for the topologies involved inside the problem. Maps from a normed space X to a metric space Y, which provide locally uniformly rotund renormings on X, are studied and a new frame for the theory is obtained, with interplay between functional analysis, optimization and topology using subdifferentials of Lipschitz functions and covering methods of metrization theory. Any one-to-one operator T from a reflexive space X into c0 (T) satisfies the authors' conditions, transferring the norm to X. Nevertheless the authors' maps can be far from linear, for instance the duality map from X to X* gives a non-linear example when the norm in X is Fréchet differentiable. This volume will be interesting for the broad spectrum of specialists working in Banach space theory, and for researchers in infinite dimensional functional analysis.Lecture notes in mathematics (Springer-Verlag) ;1951.Metric spacesContinuum (Mathematics)Mappings (Mathematics)Metric spaces.Continuum (Mathematics)Mappings (Mathematics)516.36Molto Anibal0MiAaPQMiAaPQMiAaPQBOOK9910484094503321Nonlinear transfer technique for renorming1014875UNINA
