Let $f:X\to C$ be a fibration over a function field, let $r_K:X\to R(X_K)$ be its rational quotient, and call $X_K$ dominated when it admits the dominant product-type rational map…

Let $f:X\dashrightarrow Y$ be a special fibration with $\kappa(Y,f)=-\infty$. Let $\Delta(f)$ be its base orbifold, and let $\kappa$-rationally generated mean that the general orbi…
