An equivalent way of defining such a structure is as an equivalence class of conformally related metrics with a unique affine connection Gamma((omega)), which is invariant under Weyl transformations. In a standard Weyl structure, this unique connection is assumed to be torsion-free and have vectorial non-metricity. This second view allows us to present two different generalizations of standard Weyl structures. The first one relies on conformal symmetry while allowing for a general non-metricity tensor, and the other comes from extending the symmetry to arbitrary (disformal) transformations of the metric. %R 10.1140/epjc/s10052-019-7394-z %U https://arxiv.org/abs/1906.05393 %U https://doi.org/10.1140/epjc/s10052-019-7394-z %P 878-9pp
