This paper discusses a class of doubled geometry models with diagonal metrics and proposes a hypothesis that treats them as modified bimetric gravity theories.
We discuss a class of doubled geometry models with diagonal metrics. Based on the analysis of known examples we formulate a hypothesis that supports treating them as modified bimetric gravity theories. Certain steps towards the generic case are then performed.
