On Geodesics of Sprays and Projective Completeness

Guojun Yang

Geodesics, which play an important role in spray-Finsler geometry, are integral curves of a spray vector field on a manifold. Some comparison theorems and rigidity issues are estab…

Sprays on Hamel-Funk Functions Model

Guojun Yang

Hamel functions of a spray play an important role in the study of the projective metrizability of the concerned spray, and Funk functions are special Hamel functions. A Finsler met…

On Sprays of Scalar Curvature and Metrizability

Guojun Yang

Every Finsler metric naturally induces a spray but not so for the converse. The notion for sprays of scalar (resp. isotropic) curvature has been known as a generalization for Finsl…

A Note On Conformal Vector Fields Of -Spaces

Guojun Yang

In this paper, we characterize conformal vector fields of any (regular or singular) -space with some PDEs. Further, we show some properties of conformal vector fields of a c…

On Concircular Transformations In Finsler Geometry

Zhongmin Shen, Guojun Yang

A geodesic circle in Finsler geometry is a natural extension of that in a Euclidean space. In this paper, we apply Lie derivatives and the Cartan -connection to study geodesic c…

On a Class of Complete and Projectively Flat Finsler Metrics

Guojun Yang

An -manifold is a Finsler manifold with the Finsler metric being defined by a Riemannian metric and -form on the manifold . In this paper, we class…
