powers of in the Linnik--Goldbach problem
Huixi Li, Zhixin Liu
Linnik's approximation to Goldbach's conjecture concerns the representation of sufficiently large even integers as the sum of two primes and a bounded number of powers of two. We p…
A Romanoff-type theorem for +{: a 1}
Yuchen Ding, Huixi Li, Junfeng Li
Let denote the number of prime factors of , counted with multiplicity, and put ={ 1: 2}. We prove that the sumset +{: a 1} has po…
Adjacent comparison bounds and extremal sets for Ruzsa numbers
Yuchen Ding, Huixi Li, Junfeng Li +2
Let be a positive integer and the residue class ring modulo . The Ruzsa number is defined to be the least integer such that there is a subset $\math…
An Improvement of Konstantoulas' Density Constant
Huixi Li, Zihan Zhang
Let , and define its ordered representation function The Erdos--Turan conjecture asserts that, if for all sufficiently…
Note on a conjecture of Sárközy on special sequences
Yuchen Ding, Huixi Li, Zihan Zhang
Let be an irrational number and a positive integer. Let be a polynomial with positive integer coefficients. Solving a 2001 problem of Sárközy on special seque…
On covering systems of polynomial rings over finite fields
Huixi Li, Biao Wang, Chunlin Wang +1
In 1950, Erdős posed a question known as the minimum modulus problem on covering systems for , which asked whether the minimum modulus of a covering system with distinc…
Some discussions on the Goldbach conjecture
Huixi Li
According to some discussions based on syllogism, we present results on the binary Goldbach conjecture in three categories: results that are weaker than the Goldbach conjecture, su…
On the minimum modulus problem in number fields
Huixi Li, Biao Wang, Shaoyun Yi
The minimum modulus problem on covering systems was posed in 1950 by Erdős, who asked whether the minimum modulus of a covering system with distinct moduli is bounded. In 2007, Fil…
On the connection between the Goldbach conjecture and the Elliott-Halberstam conjecture
Jing-Jing Huang, Huixi Li
In this paper we prove that the binary Goldbach conjecture for sufficiently large even integers would follow under the assumption that both the Elliott-Halberstam conjecture and a…
On a generalization of a theorem of Popov
Jing-Jing Huang, Huixi Li
In this paper, we obtain sharp estimates for the number of lattice points under and near the dilation of a general parabola, the former generalizing an old result of Popov. We appl…
On two lattice points problems about the parabola
Jing-Jing Huang, Huixi Li
We obtain asymptotic formulae with optimal error terms for the number of lattice points under and near a dilation of the standard parabola, the former improving upon an old result…
