- 요약Many theorems in modal and intuitionistic logic can be proved via a model existence argument. There are many settings, both philosophically and mathematically motivated, where the usual model construction techniques fail. This dissertation introduces a number of new techniques for building relational models for modal logic that allow us to prove otherwise unproven theorems about the logics.Most of the central results obtained in this dissertation are completeness theorems. In the case of the first chapter, we prove the completeness of logics of knowability. On the technical side, we present some ideas on how to build fairly rich models from a language that is low in expressive power, but on the philosophical side, the completeness proof also produces a collection of promising axioms for knowability. In the second chapter, we are faced with a novel semantics for indicative conditionals and epistemic modals coming from the philosophy of language. Here, we use a canonical model as an auxiliary object and define a map that extracts the data of a point of evaluation in the intended semantics from a maximal theory in the canonical model. We then obtain an axiomatization of this logic by collecting all the axioms needed to force this map to respect the structures.In the second half of the dissertation, the logics that are considered are intuitionistic. The first chapter in the intuitionistic setting concerns a modal logic of vagueness. Here, standard techniques do confirm completeness of the logic; however, because the axioms for vagueness push us into a slightly unnatural logic, we do not immediately obtain the usual nice corollaries of completeness. Careful model surgery does allow us to at least recover a partial result about the deductive system. In the final chapter, we move to the first-order setting. There is a particular roadblock that arises from the combination of a logic being all three of first-order, modal, and intuitionistic. This pushes us to develop a new model construction, the trace model. The trace model allows us to prove completeness of the logic for the expected semantics, a result that seemed out of reach when approached with a traditional canonical model strategy.
