Let $f:X\to S$ be a fibre space $X/S$, let $X_{\bar{\eta}}$ be its generic geometric fibre, and let $\omega_{X/S}$ and $\omega_{X_{\bar{\eta}}}$ denote the relative and generic-fib…

Let $f:X\to S$ be a fibre space $X/S$ whose generic geometric fibre has Kodaira dimension at least $0$. Let $\omega_{X/S}$ denote the relative canonical sheaf, and let…
