Abstract: A finite $ W$-algebra $ U(\mathfrak{g},e)$ is a certain finitely generated algebra that can be viewed as the enveloping algebra of the Slodowy slice to the adjoint orbit of a nilpotent element $ e$ of a complex reductive Lie algebra $ \mathfrak{g}$. It is possible to give the tensor product of a $ U(\mathfrak{g},e)$-module with a finite dimensional $ U(\mathfrak{g})$-module the structure of a $ U(\mathfrak{g},e)$-module; we refer to such tensor products as translations. In this paper, we present a number of fundamental properties of these translations, which are expected to be of importance in understanding the representation theory of $ U(\mathfrak{g},e)$.
