Abstract
If is a finite abelian category and is a linear right exact monad on , then the category of -modules is a finite abelian category. We give an explicit formula of the Nakayama functor of under the assumption that the underlying functor of the monad has a double left adjoint and a double right adjoint. As applications, we deduce formulas of the Nakayama functor of the center of a finite bimodule category and the dual of a finite tensor category. Some examples from the Hopf algebra theory are also discussed.
