Properties of logics of individual and group agency
We provide proof-theoretic results about deliberative STIT logic. First we present STIT logic for individual agents without time, where the problem of satisfiability has recently b...

Topology, connectedness, and modal logic
This paper presents a survey of topological spatial logics, taking as its point of departure the interpretation of the modal logic S4 due to McKinsey and Tarski. We consider the ef...

Valentini's cut-elimination for provability logic resolved
In 1983, Valentini presented a syntactic proof of cut-elimination for a sequent calculus GLSV for the provability logic GL where we have added the subscript V for "Valentini&q...

An interval logic for natural language semantics
Most temporal logics, particularly interval temporal logics, are not expressive enough to capture meanings of natural language constructions, and they are not convenient to represe...

On the intermediate logic of open subsets of metric spaces
In this paper we study the intermediate logic MLO(X) of open subsets of a metric space X. This logic is closely related to Medvedev's logic of finite problems ML. We prove sev...
