The Cichoń diagram

open access: yesJournal of Symbolic Logic, 1993
AbstractWe conclude the discussion of additivity, Baire number, uniformity, and covering for measure and category by constructing the remaining 5 models. Thus we complete the analysis of Cichoń's diagram.

Learning how to model in science classroom. Key teachers role in supporting the development of students modelling skills

open access: yesEducación Química, 2018
Modelling is a key process in the development of scientific knowledge. In order to conduct a more authentic science education, i.e., to make the processes it entails successively approximate to those of science per se, it is advocated that it should be ...

Dynamic Euler Diagram Drawing [PDF]

open access: yes, 2004
In this paper we describe a method to lay out a graph enhanced Euler diagram so that it looks similar to a previously drawn graph enhanced Euler diagram. This task is non-trivial when the underlying structures of the diagrams differ.

Planar diagrams

open access: yesCommunications in Mathematical Physics, 1978
The authors describe their method for counting planar Feynman diagrams of quantum field theory. Mathematicians who are not familiar with the current jargon of quantum field theory are likely to find this paper rather difficult to follow. In order to demonstrate the usefulness of their method, the authors calculate the ground state energy of a system of

Danser parmi les œuvres d’art

open access: yesSignata, 2020
We will examine two recent site-specific dance creations: Hofesh Schechter’s Coda and Saburo Teshigawara’s Pointed Peak. The description of the experience of these performances for an “ethnographer” viewer will lead us to use the semiotic theories of ...

Global quantum Hall phase diagram from visibility diagrams

open access: yes, 2001
We propose a construction of a global phase diagram for the quantum Hall effect. This global phase diagram is based on our previous constructions of visibility diagrams in the context of the Quantum Hall Effect.
