Abstract
We classify all possible cosmological homogeneous and isotropic Landsberg-type Finsler structures, in four dimensions. Among them, we identify viable nonstationary Finsler spacetimes, i.e., those geometries leading to a physical causal structure and a dynamical universe. Noting that any nonstationary and non-Riemannian Landsberg metric must be actually also non-Berwald (i.e., it should be a so-called "unicorn"), we construct the unique Finsler, non-Berwaldian Landsberg generalization of Friedmann-Lemaître-Robertson-Walker geometry.
