[ Abstract ]
A general hypersurface $X$ of multi-degree 2 in $(\Bbb P^1)^{d+1}$ is called a Calabi-Yau manifold of Wehler type (of dimension $d$). In this talk, after recalling some remarkable properties of $X$ found by Cantat and me, I would like to show that $X$ has a birational primitive automorphism, in particular a birational automorphism with Zariski dense orbit, in any $d \ge 2$.
