Newelski's Conjecture for $o$ -Minimal and $p$ -Adic Groups

Ningyuan Yao, Zhentao Zhang

Let $M_{0}$ denote either the field structure $Q_{p}$ of $p$ -adic numbers, or an $o$ -minimal expansion of the field structure $R$ of real numbers. We investig…

On groups definable in $p$ -adically closed fields

Anand Pillay, Ningyuan Yao, Zhentao Zhang

This paper is about the $df g$ / $f s g$ decomposition for groups $G$ definable in $p$ -adically closed fields. It is proved that for $G$ definably amenable, $G$ has a definable normal $…
