On Modal Deductive Databases
We present a query language called MDatalog, which is an extension of Datalog for multimodal deductive databases. We define modal relational algebras and give the seminaive evalua...

Verifying the Modal Logic Cube Is an Easy Task (For Higher-Order Automated Reasoners)
Prominent logics, including quantified multimodal logics, can be elegantly embedded in simple type theory (classical higher-order logic). Furthermore, off-the-shelf reasoning syste...

A Systematic Proof Theory for Several Modal Logics
The family of normal propositional modal logic systems are given a highly systematic organisation by their model theory. This model theory is generally given using Kripkean frame s...

Reasoning About Data-Parallel Pointer Programs in a Modal Extension of Separation Logic
This paper proposes a modal extension of Separation Logic [8, 11] for reasoning about data-parallel programs that manipulate heap allocated linked data structures. Separation Logi...

Lower bounds for modal logics
We give an exponential lower bound on number of proof-lines in the proof system K of modal logic, i.e., we give an example of K-tautologies 1, 2, . . . s.t. every K-proof of i must...
