Fragments of Some Subintuitionistic Logics [PDF]
In this article we determine the implicational fragments of most of the known subintuitionistic logics.

On Sub-Propositional Fragments of Modal Logic
In this paper, we consider the well-known modal logics $\mathbf{K}$, $\mathbf{T}$, $\mathbf{K4}$, and $\mathbf{S4}$, and we study some of their sub-propositional fragments, namely the classical Horn fragment, the Krom fragment, the so-called core fragment, defined as the intersection of the Horn and the Krom fragments, plus their sub-fragments obtained

We study fragments of first-order logic and of least fixed point logic that allow only unary negation: negation of formulas with at most one free variable.

A structurally complete fragment of relevant logic. [PDF]
In the fragment of relevant logic \(R\) whose connectives are \(\to\) and \(\&\), every admissible rule is derivable. The proof is a non-trivial variant of the argument in the intuitionist case.

Maximum Entropy Reasoning via Model Counting in (Description) Logics that Count
In previous work it was shown that the logic ALCME, which extends the description logic (DL) ALC with probabilistic conditionals, has domain-lifted inference.

Adding Path-Functional Dependencies to the Guarded Two-Variable Fragment with Counting [PDF]
The satisfiability and finite satisfiability problems for the two-variable guarded fragment of first-order logic with counting quantifiers, a database, and path-functional dependencies are both ExpTime-complete.

A Variant of Material Connexive Logic
The relationship between formal (standard) logic and informal (common-sense, everyday) reasoning has always been a hot topic. In this paper, we propose another possible way to bring it up inspired by connexive logic.

Querying Log Data with Metric Temporal Logic [PDF]
We propose a novel framework for ontology-based access to temporal log data using a datalog extension datalogMTL of the Horn fragment of the metric temporal logic MTL.

Reachability Logic: An Efficient Fragment of Transitive Closure Logic
Reachability logic (\({\mathcal RL}\)) is defined. It is a fragment of \(\text{FO}^2(\text{TC})\) (with Boolean variables), i.e. a fragment of the restriction of first-order logic with transitive closure in which only two variables may appear in a formula. It is shown that PDL and \(\text{CTL}^\star\) can be embedded in reachability logic.

An Efficient Algorithm for Monitoring Practical TPTL Specifications
We provide a dynamic programming algorithm for the monitoring of a fragment of Timed Propositional Temporal Logic (TPTL) specifications. This fragment of TPTL, which is more expressive than Metric Temporal Logic, is characterized by independent time ...
