Departament de Física Fonamental, Universitat de Barcelona, Diagonal 647, 08028, Barcelona, Spain aut Some Global and Local Aspects of Bigravity [Elektronische Daten] [D. Blas] We review some global and local aspects of bigravity theories concerning the causal structure of two interacting metrics. We provide some general settings where global hyperbolicity is lost even if both metrics are independently globally hyperbolic. Finally we say some words about the spectrum of these theories and their relation to the cosmological constant problem.
