RDF and Logic: Reasoning and Extension
In this paper we explore embeddings of the various kinds of RDF entailment in F-Logic. We show that the embeddings of simple, RDF, and RDFS entailment, as well as a large fragment...

Reasoning about B+ Trees with Operational Semantics and Separation Logic
The B+ tree is an ordered tree structure with a fringe list. It is the most widely used data structure for data organisation and searching in database systems specifically, and, p...

From Separation Logic to First-Order Logic
Separation logic is a spatial logic for reasoning locally about heap structures. A decidable fragment of its assertion language was presented in [1], based on a bounded model prope...

A Non-Deterministic Semantics for Tractable Inference
Unit resolution is arguably the most useful known algorithm for tractable reasoning in propositional logic. Intuitively, if one knows a, b, and a b c, then c should be an obviou...

On the Strictness of the First-Order Quantifier Structure Hierarchy over Finite Structures
One of the major interests of finite model theory is to separate the expressive power of different logics or fragments of logics. In this paper, we define a variant of EhrenfeuchtF...
