Finsler geometry is a generalization of Riemannian geometry that allows the length of a curve to be defined by an arbitrary function of the tangent vector, rather than by a quadratic form. A Finsler space is a manifold equipped with such a length function, called a Finsler metric¹.
Three dimensional Finsler spaces are Finsler spaces of dimension three. They have applications in various fields of mathematics and physics, such as differential geometry, dynamical systems, relativity theory, and cosmology²³.
Some examples of applications of three dimensional Finsler spaces are:
- The study of geodesics and curvature properties of Finsler spaces, such as C-reducible, semi C-reducible, P-reducible, L-reducible, and S3-like or S4-like Finsler spaces² .
- The classification and characterization of homogeneous and left-invariant Finsler metrics on Lie groups and symmetric spaces² .
- The investigation of special classes of Finsler metrics, such as Matsumoto metrics, Randers metrics, cubic metrics, fourth root metrics, and generalized symmetric metrics² .
- The exploration of the connections between Finsler geometry and relativity theory, such as the equivalence principle, the gravitational field equations, the cosmological models, and the gravitational lensing³ .
