Correlation properties of interleaved Legendre sequences and Ding-Helleseth-Lam sequences
Sequences with optimal autocorrelation properties play an important role in wireless communication, radar and cryptography. Interleaving is a very important method in constructing the optimal autocorrelation sequence.

The first ascent of size $d$ or more in compositions [PDF]
A composition of a positive integer $n$ is a finite sequence of positive integers $a_1, a_2, \ldots, a_k$ such that $a_1+a_2+ \cdots +a_k=n$. Let $d$ be a fixed nonnegative integer.

Almost primes in generalized Piatetski-Shapiro sequences
We consider a generalization of Piatetski-Shapiro sequences in the sense of Beatty sequences, which is of the form $\left( \left\lfloor{\alpha n^c + \beta}\right\rfloor \right)_{n = 1}^{\infty} $ with real numbers $ \alpha {\geqslant} 1, c > 1 $ and $

On the high-th mean of one special character sums modulo a prime
Using the elementary method of the classical Gauss sums and the properties of character sums, we study a linear recurrence formula about the form $ G\left(n\right) = 1+\sum_{a = 1}^{p-1}\left(\frac{a^2+n\bar{a}^2}{p}\right) $ and about the mean value of $

On the fourth power mean of one special two-term exponential sums
The main purpose of this paper is using the elementary methods and the number of the solutions of some congruence equations to study the calculating problem of the fourth power mean of one special two-term exponential sums, and give an exact calculating ...

On the K-th power mean of one kind generalized cubic Gauss sums
The main purpose of this paper is using the elementary methods and properties of the recurrence sequence to study the calculating problem of the $ k $-th power mean of one kind generalized cubic Gauss sums, and give an exact calculating formula for it.

Apollonian circle packings: Dynamics and Number theory [PDF]
We give an overview of various counting problems for Apollonian circle packings, which turn out to be related to problems in dynamics and number theory for thin groups.

Binary sequences and lattices constructed by discrete logarithms
In 1997, Mauduit and Sárközy first introduced the measures of pseudorandomness for binary sequences. Since then, many pseudorandom binary sequences have been constructed and studied. In particular, Gyarmati presented a large family of pseudorandom binary
