Mentorat : appel pour les mentoré·es
Suite à notre appel à mentors, nous invitons désormais les étudiant·es et les jeunes chercheur·es à candidater pour devenir mentoré·es.
De nombreux étudiant·es et jeunes chercheur·es rencontrent des obstacles importants pour accéder à un mentorat académique structuré.
Learning over Structured High-Dimensional Objects: Theory and Complexity
Many modern, large-scale datasets are structured as graphs, matrices, tensors, and other combinatorial objects. A central challenge across mathematics, statistics, and theoretical computer science is to understand the limits of inference, when these limits can be achieved computationally, and where fundamental barriers arise.
Mentorat
Nous sommes ravis d'annoncer que, dans la poursuite de sa mission de promotion de la recherche en mathématiques avec les pays en développement, le CIMPA lance aujourd'hui un programme de mentorat.
Dans un premier temps, nous invitons les membres de notre communauté à devenir mentors.
Geometric topology and its friends
While landmark achievements by Perelman, Agol, and others have recently resolved major questions in dimension 3, the field of low-dimensional topology remains vibrant. Significant challenges persist—such as the L-space conjectureand the smooth Poincaré conjecture in dimension 4—alongside emerging questions at the intersection of various mathematical disciplines.
