Abstract
We shall give a sufficient condition on the primitivity of a birational automorphism of a Calabi–Yau manifold in purely algebro-geometric terms. As an application, we shall give an explicit construction of Calabi–Yau manifolds of Picard number $2$ of any dimension $\geq 3$, with primitive birational automorphisms of first dynamical degree $\gt 1$.
