L’objet de cette thèse est l’étude des catégories singulières des k-algèbres associatives surun anneau commutatif k. On développe la théorie de Morita pour les catégories singulières. Plus précisément, on propose une définition d’équivalence singulière à la Morita avec niveau, qui généralise la notion d’équivalence stable à la Morita introduite par Michel Broué. On montre qu’une équivalence dérivée de type standard induit une équivalence singulière à la Morita avec niveau. La deuxième partie de cette thèse est l’étude de la cohomologie de Hochschild singulière HH_sg(A,A) c’est-à-dire, l’espace des morphismes de A vers A[i] dans la catégorie singulière Dsg(A Aop) pour tous les nombres entiers i. Similaire à la cohomologie de Hochschild HH_...
