Observer dependent background geometries — •Manuel Hohmann — Tartu University, Estonia
Various approaches to quantum gravity suggest a breaking of general covariance or local Lorentz invariance via the introduction of preferred foliations of spacetime or preferred timelike vector fields. Physical quantities may then obtain a non-tensorial dependence on the observer performing their measurement. We discuss observer dependent geometries which may serve as backgrounds for physical theories, in particular for gravity, and can be described in the languages of Finsler and Cartan geometry.
