Infinitely $p$-divisible points on abelian varieties defined over function fields of characteristic $p>0$

In this article we consider some questions raised by F. Benoist, E. Bouscaren and A. Pillay. We prove that infinitely $p$-divisible points on abelian varieties defined over function fields of transcendence degree one over a finite field are necessarily torsion points. We also prove that when the endomorphism ring of the abelian variety is $\text{mZ}$ then there are no infinitely $p$-divisible points of order a power of $p$.
