We introduce the notions of categorical integrals and categorical cointegrals of a finite tensor categoryby using a certain adjunction betweenand its Drinfeld center. These notions can be identified with integrals and cointegrals of a finite-dimensional Hopf algebraHifis the representation category ofH. We generalize basic results on integrals and cointegrals of a finite-dimensional Hopf algebra (such as the existence, the uniqueness, and the Maschke theorem) to finite tensor categories. Motivated by results of Lorenz, we also investigate relations between categorical integrals and morphisms factoring through projective objects. Finally, we extend then-th indicator of a finite-dimensional Hopf algebra introduced by Kashina, Montgomery and Ng to finite tensor categories.
