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 $…

On definable $f$ -generic groups and minimal flows in $p$ -adically closed fields

Ningyuan Yao, Zhentao Zhang

Let $X$ be a definable group definable over a small model $M_{0}$ . Recall that a global type $p$ on $X$ is definable $f$ -generic over $M_{0}$ if every left translate of $p$ is definabl…

Definably Topological Dynamics of $p$ -Adic Algebraic Groups

Jiaqi Bao, Ningyuan Yao

We study the $p$ -adic algebraic groups $G$ from the definable topological-dynamical point of view. We consider the case that $M$ is an arbitrary $p$ -adic closed field and $G$ an al…

On Dimensions, Standard Part Maps, and $p$ -Adically Closed Fields

Ningyuan Yao

The aim of this paper is to study the dimensions and standard part maps between the field of $p$ -adic numbers $Q_{p}$ and its elementary extension $K$ in the language of…

Definable Topological Dynamics for Trigonalizable Algebraic Groups over Qp

Ningyuan Yao

We study the flow (G(Qp); SG(Qp)) of trigonalizable algebraic group acting on its type space, focusing on the problem raised in [17] of whether weakly generic types coincide with a…
