Abstract:   (1646 Views)
In this paper‎, ‎we point out that the class of Douglas Kropina metrics is closed under conformal transformations via navigation data‎. ‎Then‎, ‎we characterize conformally weakly Berwald Kropina metrics‎. ‎Finally‎, ‎we characterize the local structure of Douglas Kropina metrics of weakly isotropic flag curvature‎. 
Keywords: Kropina metric‎, Douglas Kropina metric, Conformally weakly Berwald Kropina metric‎, ‎Navigation data.‎, ‎flag curvature.
