Logique et mathématiques chez Hegel. Les formalisations de la logique en question
Mosaïque, 2013 Quoi qu’on n’ignore pas les développements importants et positifs que Hegel consacre à la mathématique de l’infini, aux calculs différentiel et intégral, son discours est dans l’ensemble très sévère à l’égard des mathématiques. Pour l’expliquer,

Em Teia, 2018 La notion d'obstacles a acquis un espace d'attention garanti dans le domaine de la didactique des mathématiques, initialement introduit et appliqué au domaine des mathématiques, a partir du travail de quelques spécialistes français, dans les années 1980.

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

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 ...

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

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,

Annales de Didactique et de Sciences Cognitives, 2015 It seems obvious that teacher educators should themselves be trained. Nevertheless, rare are research studies that consider this issue. In this paper we trace the history and present the theoretical background of a university program for training ...
