A new topology on the space of Lorentzian metrics on a fixed manifold

- Johan Noldus
- Physics
- 7 December 2002

We give a covariant definition of closeness between (time-oriented) Lorentzian metrics on a manifold M, using a family of functions which measure the difference in volume form on one hand and, on the… Expand

A Lorentzian Gromov–Hausdorff notion of distance

- Johan Noldus
- Physics, Mathematics
- 22 August 2003

This paper is the first of three in which I study the moduli space of isometry classes of (compact) globally hyperbolic spacetimes (with boundary). I introduce a notion of Gromov?Hausdorff distance… Expand

The moduli space of isometry classes of globally hyperbolic spacetimes

- L. Bombelli, Johan Noldus
- Physics
- 11 February 2004

This paper is part of a research programme on the structure of the moduli space of Lorentzian geometries, a Lorentzian analogue of Gromov–Hausdorff theory based on the use of the Lorentz distance as… Expand

Lorentzian Manifolds and Causal Sets as Partially Ordered Measure Spaces

- L. Bombelli, Johan Noldus, Julio G. Tafoya
- Physics
- 4 December 2012

We consider Lorentzian manifolds as examples of partially ordered measure spaces, sets endowed with compatible partial order relations and measures, in this case given by the causal structure and the… Expand

A Proof of the Falsity of the Axiom of Choice.

- Johan Noldus
- Mathematics
- 1 December 2017

We observe two things in this paper : namely that the Banach Tarski paradox is false and that the correct part of the proof leads to a violation of the axiomof choice.

- Johan Noldus
- 2008

This paper can be seen as an exercise in how to adapt quantum mechanics from a strict relativistic perspective while being respectful and critical towards the experimental achievements of the… Expand

A Higher Language for Mathematics.

- Johan Noldus
- Mathematics
- 1 June 2016

We extend the language of mathematics by generalizing the logical implication and negation. As such, our framework serves as an extension of intuitionistic logic.
