Universidad de Zaragoza (orcid)0000-0003-4480-6535 Infinitesimal Time Reparametrisation and Its Applications 2022 Access copy available to the general public Unrestricted A geometric approach to Sundman infinitesimal time-reparametrisation is given and some of its applications are used to illustrate the general theory. Special emphasis is put on geodesic motions and systems described by mechanical type Lagrangians. The Jacobi metric appears as a particular case of a Sundman transformation. © 2022, The Author(s). info:eu-repo/grantAgreement/ES/DGA/E48-20R info:eu-repo/grantAgreement/ES/MICINN/PGC2018-098265-B-C31 info:eu-repo/grantAgreement/ES/MINECO/PGC2018-098265-B-C33 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 0.7 2022 PHYSICS, MATHEMATICAL 51 / 56 = 0.911 2022 Q4 T3 MATHEMATICS, APPLIED 229 / 267 = 0.858 2022 Q4 T3 0.308 2022 Statistical and Nonlinear Physics 2022 Q3 Mathematical Physics 2022 Q3 1.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez, E.
