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