Bridging de Bruijn Indices and Variable Names in Explicit Substitutions Calculi
Calculi of explicit substitutions have almost always been presented using de Bruijn indices with the aim of avoiding -conversion and being as close to machines as possible. De Bru...

An Analysis of (Linear) Exponentials Based on Extended Sequents
We apply the 2-sequents approach to the analysis of several calculi derived from linear logic. We present a uniform formal system for Linear Logic, Elementary Linear Logic and Lig...

Towards Structurally-Free Theorem Proving
Is it possible to compute in which logics a given formula is deducible? The aim of this paper is to provide a formal basis to answer positively this question in the context of sub...

A Brief Note About Rott Contraction
One of the ways to model contraction functions for belief sets is epistemic entrenchment. The first step was provided by G¨ardenfors in [5], who defined epistemic entrenchment ...
