Ordinary varieties with trivial canonical bundle are not uniruled
We prove that smooth, projective, K-trivial, weakly ordinary varieties over a perfect field of characteristic [Formula: see text] are not geometrically uniruled. We also show a singular version of our theorem, which is sharp in multiple aspects. Our work, together with Langer’s results, implies that...
