A Weyl-type theorem for Diophantine approximations driven by LCA groups and applications

Aihua Fan

We investigate actions of locally compact Abelian (LCA) groups on the torus $T^{n}$ , motivated by their close connection with Diophantine approximation. While Kronecker's th…

Khintchin conjecture and related topics

Aihua Fan, Shilei Fan, Hervé Queffélec +1

Motivated by Khintchin's 1923 conjecture, refuted by Marstrand in 1970, we study the Khintchin class of functions associated to a given increasing sequence of integers. When the Kh…

Non-Archimedean Koksma Theorems and Dimensions of Exceptional Sets

Aihua Fan, Shilei Fan, Hanfei Ye

We establish a non-Archimedean analogue of Koksma's theorem. For a local field F of characteristic zero, we prove that the sequence ([αx^n]) is uniformly distributed in the valuati…

Exponential Riesz bases in non-Archimedean locally compact Abelian groups

Aihua Fan, Shilei Fan

This paper establishes two fundamental results on the existence of exponential Riesz basis in non-Archimedean locally compact Abelian groups: the existence of Riesz basis of expone…

Computation of Lyapunov exponents of matrix products

Aihua Fan, Evgeny Verbitskiy

For $m$ given square matrices $A_{0}, A_{1}, \dots, A_{m - 1}$ ( $m \geq 2$ ), one of which is assumed to be of rank $1$ , and for a given sequence $(ω_{n})$ in $\{0,1, \cdots, m-1\}^\mathbb{N…

$p$ -adic rational maps having empty Fatou set

Aihua Fan, Shilei Fan, Yahia Mwanis +1

On any finite algebraic extension $K$ of the field $\Q_p$ of $p$ -adic numbers, there exist rational maps $ϕ \in K (z)$ such that dynamical system $(P^{1} (K), ϕ)$ has empty Fa…
