Aux origines de la philosophie contemporaine des mathématiques : Kant, Hegel, Bolzano
Characteristica Universalis Journal, 2020 Dans cet article, nous étudierons la logique philosophique de Kant (1724-1804), de Hegel (1770-1831) et de Bolzano (1781-1848) relativement aux questions mathématiques. Nous tenterons de montrer que leurs trois philosophies sont fortement influencées par

FORMATION MATHÉMATIQUE DES ENSEIGNANTS DU SECONDAIRE
Em Teia, 2010 Nous proposons dans ce texte une réflexion et une discussion sur la formation mathématique des futurs enseignants au secondaire. Cette préparation mathématique semble souvent considérée comme un allant de soi.

Entrer dans un genre procédural : l’écriture d’un programme de construction en géométrie
Annales de Didactique et de Sciences Cognitives, 2019 The discovery of a procedural genre: the writing of a program of construction in geometry. The writing of a program of geometrical construction is a particular kind of task in so far as it requires the respect of some strict expectations in addition to ...

Advanced Energy Materials, EarlyView.A combination of discrete and finite element method models for the current collector deformation and electrochemical performance analysis, respectively. The models are calibrated and validated with electrochemical and imaging data of hard carbon electrodes. These electrodes were manufactured with different parameters (slurry solid contents of 35 and 40

Canadian Journal of Statistics, EarlyView.Abstract Irregular observation times are common in longitudinal observational studies and can affect causal inferences. We use data from electronic health records of Kaiser Permanente Washington patients in the United States who initiated an antidepressant medication between 2008 and 2018, with a confirming diagnosis of depression. We are interested in

De la lecture à la résolution de problèmes: des habiletés spécifiques à développer
Canadian Journal of Education, 2012 La réussite des élèves en mathématiques, particulièrement la réussite en résolution de problèmes écrits, a souvent été associée aux compétences en lecture. Si plusieurs recherches ont permis d’établir clairement un lien entre le rendement en lecture des

Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Path Degeneracy and Applications
Journal of Graph Theory, EarlyView.ABSTRACT In this work, we relate girth and path‐degeneracy in classes with sub‐exponential expansion, with explicit bounds for classes with polynomial expansion and proper minor‐closed classes that are tight up to a constant factor (and tight up to second order terms if a classical conjecture on existence of g $g$‐cages is verified). As an application,
