The optimal hypercontractive constants for $Z_{3}$ and biased Bernoulli random variables

Jie Cao, Shilei Fan, Yong Han +2

We resolve a folklore problem of determining the optimal hypercontractive constants $r_{p, q} (Z_{3})$ for the cyclic group $Z_{3}$ for all $1 < p < q < \infty$ . More p…

Periodicity of tiles in finite Abelian groups

Shilei Fan, Tao Zhang

In this paper, we introduce the periodic tiling (PT) property for finite abelian groups. A finite abelian group is said to have the PT property if every non-periodic set that tiles…

Tiling the field $Q_{p}$ of $p$ -adic numbers by a function

Shilei Fan

This study explores the properties of the function which can tile the field $Q_{p}$ of $p$ -adic numbers by translation. It is established that functions capable of tiling $\…

The structure of tiles in $Z_{p^{n}} \times Z_{q}$ and $Z_{p^{n}} \times Z_{p}$

Shilei Fan, Mamateli Kadir, Peishan Li

In this paper, we provide a geometric characterization of tiles in the finite abelian groups $ \mathbb{Z}_{p^n} \times \mathbb{Z}_q $ and \( \mathbb{Z}_{p^n} \times \mathbb{Z}_p…
