For n 2, we consider V R n the class of germs of real analytic vector fields on R 2 , 0 with zero (n − 1)-jet and nonzero n-jet. We prove, for generic germs of V R n , that the real-formal orbital equivalence implies the real-analytic orbital equivalence, that is, the real-formal orbital rigidity takes place. This is the real analytic version of Voronin's formal orbital rigidity theorem.Keywords Nondicritic vector fields · Real-formal orbital equivalence · Real-analytic orbital equivalence · Real-formal orbital rigidity · Desingularization of singularities · Holonomy group Mathematics Subject Classification (2010) 32S65 · 37F75 · 32M25 · 34A25 · 34C20 · 57R30
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
