Abstract:

In this article we discuss two alternative proposals for neighbourhood semantics (which we call strict and loose neighbourhood semantics, N_= and N_\subseteq respectively) that have been previously introduced in the literature. Our main tools are suitable notions of bisimulation. While an elegant notion of bisimulation exists for N_\subseteq, the required bisimulation for N_= is rather involved. We propose a simple extension of N_= with a universal modality that we call N_=(E), which comes together with a natural notion of bisimulation. We also investigate the complexity of the satisfiability problem for N_\subseteq and N_=(E).
