Norming in discrete crossed products

Let G↷A be an action of a discrete group on a unital C∗-algebra by ∗-automorphisms. In this note, we give two sufficient dynamical conditions for the C∗-inclusion A⊆A⋊rG to be norming in the sense of Pop, Sinclair, and Smith. As a consequence of our results, when A is separable or simple, the inclusion A⊆A⋊rG is norming, provided it has a unique pseudo-expectation in the sense of Pitts.
