This paper studies a general notion of flatness in the enriched context: P-flatness where the parameter P stands for a class of presheaves. One obtains a completion of a category A by considering the category F latP(A) of P-flat presheaves over A. This completion is related to the free cocompletion under a class of colimits defined by Kelly. We define a notion of Q-accessible categories for a f...
