Making first order linear logic a generating grammar [PDF]
It is known that different categorial grammars have surface representation in a fragment of first order multiplicative linear logic (MLL1). We show that the fragment of interest is equivalent to the recently introduced extended tensor type calculus (ETTC)

Positive First-order Logic on Words and Graphs [PDF]
We study FO+, a fragment of first-order logic on finite words, where monadic predicates can only appear positively. We show that there is an FO-definable language that is monotone in monadic predicates but not definable in FO+.

Interactive Interpretation Viewer for Typed First-order Logic
This poster describes the Interactive Interpretation Viewer - IIV, for finite interpretations in typed first-order logic written in the (new) TPTP format for interpretations.

Successor-Invariant First-Order Logic on Classes of Bounded Degree [PDF]
We study the expressive power of successor-invariant first-order logic, which is an extension of first-order logic where the usage of an additional successor relation on the structure is allowed, as long as the validity of formulas is independent of the ...

Game semantics for first-order logic [PDF]
We refine HO/N game semantics with an additional notion of pointer (mu-pointers) and extend it to first-order classical logic with completeness results.

Separating Regular Languages with First-Order Logic [PDF]
Given two languages, a separator is a third language that contains the first one and is disjoint from the second one. We investigate the following decision problem: given two regular input languages of finite words, decide whether there exists a first ...

GEOMETRISATION OF FIRST-ORDER LOGIC [PDF]
AbstractThat every first-order theory has a coherent conservative extension is regarded by some as obvious, even trivial, and by others as not at all obvious, but instead remarkable and valuable; the result is in any case neither sufficiently well-known nor easily found in the literature.

Lindstrom theorems for fragments of first-order logic [PDF]
Lindstr\"om theorems characterize logics in terms of model-theoretic conditions such as Compactness and the L\"owenheim-Skolem property. Most existing characterizations of this kind concern extensions of first-order logic.

Some Turing-Complete Extensions of First-Order Logic [PDF]
We introduce a natural Turing-complete extension of first-order logic FO. The extension adds two novel features to FO. The first one of these is the capacity to add new points to models and new tuples to relations.

First-Order Classical Modal Logic [PDF]
This paper focuses on extending to the first order case the semantical program for modalities first introduced by Dana Scott and Richard Montague. We focus on the study of neighborhood frames with constant domains and we offer in the first part of the paper a series of new completeness results for salient classical systems of first order modal logic.
