Finsler Geometry  

In General > s.a. Gauss-Bonnet; lie group.
* Idea: Can be locally anisotropic, and has been used to model/explain anisotropy in cosmology.

Additional Structure and Special Cases
* Randers spaces RFn: Finsler spaces Fn = (M, + ) equipped with the Cartan non-linear connection, introduced by R S Ingarden.
* Ingarden spaces IFn: Finsler spaces Fn = (M, + ) equipped with the Lorentz non-linear connection, introduced by R Miron.

Generalizations > s.a. non-commutative geometry; Riemann-Cartan; types of fiber bundles.
@ Pseudo-Finsler structures: Skakala & Visser a0806, a0810-in [and birefringent optics].
@ Finsler-Lagrange spaces: Vacaru a0707, IJGMP(08)-a0801, SIGMA(08)-a0806 [rev, general relativity and string theory]; Miron RPMP(06).

And Physics > s.a. chaos in Bianchi models; doubly special relativity; modified lorentz symmetry; path integrals; Very Special Relativity.
* Motivation: A Finsler structure is one possible way to model a small-scale breaking of Lorentz invariance.
