Abstract

We present a general formalism to formulate Bell's theorem, no-hidden variables proofs and extended Wigner's friend scenarios. This common mathematical framework allows to bridge the differences between an old (short-lived) research program (that of modal interpretations) and the more recent literature on perspectival anti-realist interpretations. We find that our unifying mathematical approach gives a clear content to the technical aspect of various no-go theorem, and provides new insights on their conceptual role by allowing comparison between different research programs.
