--- res: bibo_abstract: - In this article we study some geometric properties of proximally smooth sets. First, we introduce a modification of the metric projection and prove its existence. Then we provide an algorithm for constructing a rectifiable curve between two sufficiently close points of a proximally smooth set in a uniformly convex and uniformly smooth Banach space, with the moduli of smoothness and convexity of power type. Our algorithm returns a reasonably short curve between two sufficiently close points of a proximally smooth set, is iterative and uses our modification of the metric projection. We estimate the length of the constructed curve and its deviation from the segment with the same endpoints. These estimates coincide up to a constant factor with those for the geodesics in a proximally smooth set in a Hilbert space.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Grigory foaf_name: Ivanov, Grigory foaf_surname: Ivanov foaf_workInfoHomepage: http://www.librecat.org/personId=87744F66-5C6F-11EA-AFE0-D16B3DDC885E - foaf_Person: foaf_givenName: Mariana S. foaf_name: Lopushanski, Mariana S. foaf_surname: Lopushanski bibo_doi: 10.1007/s11228-021-00612-1 dct_date: 2021^xs_gYear dct_identifier: - UT:000705774800001 dct_isPartOf: - http://id.crossref.org/issn/0927-6947 - http://id.crossref.org/issn/1877-0541 dct_language: eng dct_publisher: Springer Nature@ dct_title: Rectifiable curves in proximally smooth sets@ ...
