- Identified conditions for the existence of a redshift potential
- Provided examples with spherically symmetric and cosmological Finsler spacetimes

## Abstract

We derive and discuss a general redshift formula in Finsler spacetimes. The condition for the existence of a redshift potential is worked out. The results are illustrated with two examples, one refering to a spherically symmetric and static Finsler spacetime and the other to a cosmological Finsler spacetime.
