The Characterizations and Constructions of Sprays of Isotropic Curvature
文献摘要:
This paper discusses the sprays of isotropic curvature.We first determine the relationship between x-curvatures of two projectively related sprays.Based on this,we find an approach to construct sprays of isotropic curvature and find infinitely many sprays of isotropic curvature via some known sprays of isotropic curvature.In particular,by using famous Funk metric Θ,we can construct infinitely many sprays of isotropic curvature,some of which can be induced by Finsler metrics,but others cannot be induced by any Finsler metric.
