A number theoretic characterization of $E$-smooth and (FRS) morphisms: estimates on the number of $\mathbb{Z}/p^k\mathbb{Z}$-points

Raf Cluckers, Itay Glazer, Yotam I. Hendel

We provide uniform estimates on the number of $\mathbb{Z}/p^k\mathbb{Z}$-points lying on fibers of flat morphisms between smooth varieties whose fibers have rational singularitie…
