Matrix Kloosterman sums and product-trace estimates for semisimple algebras

Xuejun Guo, Chen Lin, Chenhao Tang

Let $k = F_{q}$ , $E = F_{q^{n}}$ and $Tr = Tr_{E / k}$ . For $r \geq 2$ , $a \in k^{\times}$ and $x \in E^{\times}$ , let $N (E, r, x, a)$ be the number of $r…

On the Fractional Parts of Polynomials Modulo $p$

Xuejun Guo, Chen Lin, Zhefeng Xu

We study a half-interval distribution problem for polynomial residues modulo an odd prime $p$ : how often the fractional part of $I ¨ (x) / p$ lies in the upper half of the unit interva…

The $p$ -rationality of $Q (- (k p + m))$ and $Q (p (p + 1))$

Chen Lin, Xuejun Guo

In this paper, we construct new families of imaginary and real quadratic fields that are $p$ -rational. In the imaginary case, we prove that for any positive integer $k$ and any int…

Counting Polynomial-type Exceptional Units on Algebraic Varieties over Number Fields

Chen Lin, Kaihan Tang

Previous research on exceptional units has primarily focused on the ring of rational integers or abstract finite rings, often restricted to linear or quadratic constraints. In this…

Kneser's theorem for codes and $ℓ$ -divisible set families

A $k$ -wise $ℓ$ -divisible set family is a collection $F$ of subsets of ${1, \dots, n}$ such that any intersection of $k$ sets in $F$ has cardinality div…

The asymptotic estimation of prime ideals in imaginary quadratic fields and Chebyshev's bias

Chen Lin, Chenhao Tang, Xuejun Guo

We study the asymptotic estimation of prime ideals that satisfy certain congruence and argument conditions in imaginary quadratic fields. We also discuss the phenomenon of Chebyshe…
