Approximate fixed points of nonexpansive functions in product spaces Kohlenbach, Ulrich Leustean, Laurentiu Proof mining fixed point theory approximated fixed points nonexpansive functions product spaces In this talk, we present another case study in the general program of proof mining in fixed point theory. Thus, we generalize results obtained by W. Kirk in the theory of approximated fixed points of nonexpansive mappings in product spaces Schloss Dagstuhl – Leibniz-Zentrum für Informatik Ulrich Kohlenbach and Laurentiu Leustean 2006 Is Part Of Dagstuhl Seminar Proceedings, Volume 5021, Mathematics, Algorithms, Proofs (2006) InProceedings Text doc-type:ResearchArticle publishedVersion application/pdf doi:10.4230/DagSemProc.05021.6 urn:nbn:de:0030-drops-4330 https://drops.dagstuhl.de/entities/document/10.4230/DagSemProc.05021.6 eng https://creativecommons.org/licenses/by/4.0/legalcode
