Abstract

In this paper, we proved two results regarding the arithmetics of separably A1\mathbb{A}^1-connected varieties of rank one. First we proved over a large field, there is an A1\mathbb{A}^1-curve through any rational point of the boundary, if the boundary divisor is smooth and separably rationally connected. Secondly, we generalize a theorem of Hassett-Tschinkel for the Zariski density of integral points over function fields of curves.
