Dans cette thèse on étudie certaines constructions géométriques qui apparaissent naturellement dans le contexte des modèles sigma, leur jaugeage et supersymétrisation. La thèse comprend trois parties. La première partie (chapitres 1 et 2) contient des faits issus de la géométrie différentielle classique et de la géométrie graduée nécessaires pour comprendre les résultats clés de la thèse. On survole la géométrie liée aux variétés de Poisson et variétés symplectiques. On généralise ces notions aux variétés de Dirac et variétés n-plectiques, et établit leur liens avec les algebroïdes de Courant. Le langage principal utilisé dans la thèse pour la description mathématique des modèles sigma – c'est la géométrie graduée – on définit donc des base...
