Equilibrium measures of the natural extension of -shifts [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2021
AbstractWe give a necessary and sufficient condition on $\beta $ of the natural extension of a $\beta $ -shift, so that any equilibrium measure for a function of bounded total oscillations is a weak Gibbs measure.

Deformation classes in generalized Kähler geometry

open access: yesComplex Manifolds, 2020
We describe natural deformation classes of generalized Kähler structures using the Courant symmetry group, which determine natural extensions of the notions of Kähler class and Kähler cone to generalized Kähler geometry.

On geometric extension of polynomials on Banach spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We consider some questions related to Aron-Berner extensions of polynomials on infinitely dimensional complex Banach spaces, using natural extensions of their zeros.

Extensions of symmetric operators I: The inner characteristic function case

open access: yesConcrete Operators, 2015
Given a symmetric linear transformation on a Hilbert space, a natural problem to consider is the characterization of its set of symmetric extensions. This problem is equivalent to the study of the partial isometric extensions of a fixed partial isometry.

The Quantified Argument Calculus and Natural Logic

open access: yesDialectica, 2022
The formalisation of natural language arguments in a formal language close to it in syntax has been a central aim of Moss's Natural Logic. I examine how the Quantified Argument Calculus (Quarc) can handle the inferences Moss has considered.

A natural extension of natural deduction [PDF]

open access: yesJournal of Symbolic Logic, 1984
One of the main ideas of calculi of natural deduction, as introduced by Jaśkowski and Gentzen, is that assumptions may be discharged in the course of a derivation. As regards sentential logic, this conception will be extended in so far as not only formulas but also rules may serve as assumptions which can be discharged.

Computing preferred extensions in abstract argumentation : a SAT based approach [PDF]

open access: yes, 2013
This paper presents a novel SAT-based approach for the computation of extensions in abstract argumentation, with focus on preferred semantics, and an empirical evaluation of its performances.

Les accrus de frêne dans les Pyrénées Centrales : un avenir énergétique local ?

open access: yesRevue de Géographie Alpine, 2012
While the agricultural economy of Central Pyrenean is steadily declining, natural forest stands progress on agricultural mountainous meadows. For these forest extensions, we define the economic conditions of a new fuel-wood local economy.
