Explicit mathematics: power types and overloading
Systems of explicit mathematics provide an axiomatic framework to represent programs and to prove properties of them. We introduce such a system with a new form of power types usi...

Finite information logic
We introduce a generalization of Independence Friendly (IF) logic in which Eloise (the player) is restricted to a finite amount of information about Abelard's ('s) move...

Elementary arithmetic
Abstract. There is a very simple way in which the safe/normal variable discipline of Bellantoni-Cook recursion (1992) can be imposed on arithmetical theories like PA: quantify over...

Safe beliefs for propositional theories
We propose an extension of answer sets, that we call safe beliefs, that can be used to study several properties and notions of answer sets and logic programming from a more genera...

Polarized and focalized linear and classical proofs
We give the precise correspondence between polarized linear logic and polarized classical logic. The properties of focalization and reversion of linear proofs are at the heart of ...

Logical aspects of Cayley-graphs: the group case
Abstract. We prove that a finitely generated group is context-free whenever its Cayleygraph has a decidable monadic second-order theory. Hence, by the seminal work of Muller and Sc...

Dynamic topological logic
Dynamic Topological Logic provides a context for studying the confluence of the topological semantics for S4, based on topological spaces rather than Kripke frames; topological dy...
