The movable cone of Calabi--Yau threefolds in ruled Fano manifolds

We describe explicitly the chamber structure of the movable cone for a general complete intersection Calabi–Yau threefold in a non-split $(n + 4)$-dimensional$$\mathbb{P}$^{n}$-ruledFanomanifoldofindex$n + 1$ and Picard number two. Moreover, all birational minimal models of such Calabi–Yau threefolds are found whose number is finite.
