Principal Non-singularity of Fourier Matrices on $Z_{p} \times Z_{q}$ and $Z_{2}^{k} \times Z_{q}$

Weiqi Zhou

Let $F_{n}$ be the $n \times n$ Fourier matrix on the cyclic group $Z_{n}$ , a renowned theorem of Chebotarëv asserts that all minors in $F_{n}$ for prime $n$ are non-zero. In this…

On Tiling and Spectral Sets in $Z_{p^{2}} \times Z_{p^{2}}$

Weiqi Zhou

Let $p$ be a prime number, it is shown that tiling and spectral sets coincide in $Z_{p^{2}} \times Z_{p^{2}}$ by considering equivalently symplectic spectral pairs. The m…
