Generalized Quantifiers Meet Modal Neighborhood Semantics Johan van Benthem, Dag Westerstähl Abstract: Neighborhood models for modal logic are generalized quantifiers, parametrized to points in the domain of objects/worlds. We explore this analogy further, connecting generalized quantifier theory and modal neighborhood logic. We find interesting analogies between conservativity for linguistic quantifiers and the locality of modal logic, the role of invariances in both fields, and we give some new completeness results for modal logics of linguistically motivated classes of generalized quantifiers.
