GRAID Graduate Assistantships in Developing Countries.
La Commission pour les Pays en Développement de l'Union Mathématique Internationale a créé le programme GRAID (Graduate Assistantships in Developing Countries). Son objectif est de permettre à des étudiants de pays défavorisés de poursuivre leurs études et de préparer un master ou une thèse en mathématiques dans leur pays, grâce à un soutien financier minimal. Les dons sont à adresser au CIMPA (Centre International de Mathématiques Pures et Appliquées), association reconnue d'utilisé publique, ce qui permet aux contribuables français de bénéficier d'une déduction fiscale pour leurs dons - voir le site du CIMPA Donation à GRAID (Graduate Research Assistantships In Developing countries)
Run for GRAID contribue au financement. Voir mon compte facebook, les sites Run For Graid et Angel Pineda Running for GRAID.
Concert Solidaire à Limours, La Scène, samedi 20 novembre 2021 à 20h30. Au profit de trois associations dont Run For Graid.
