On the $p$ -adic distribution of torsion values for a section of an abelian scheme

Brian Lawrence, Umberto Zannier

Let $A \to S$ be an abelian scheme over a $p$ -adic field, and let $s : S \to A$ be a section. We study the torsion locus $\bigcup \limits_{n \geq 1} s^{-1}(A[n…

D-finiteness, rationality, and height

Jason P. Bell, Khoa D. Nguyen, Umberto Zannier

Motivated by a result of van der Poorten and Shparlinski for univariate power series, Bell and Chen prove that if a multivariate power series over a field of characteristic 0 is D-…
