Difference sets and Polynomials of prime variables

Hongze Li, Hao Pan

Let ψ(x) be a polynomial with rational coefficients. Suppose that ψhas the positive leading coefficient and zero constant term. Let A be a set of positive integers with the positiv…

On value sets of polynomials over a field

Zhi-Wei Sun

Let F be any field. Let p(F) be the characteristic of F if F is not of characteristic zero, and let p(F)=+\infty otherwise. Let A_1,...,A_n be finite nonempty subsets of F, and let…

Covers of the integers with odd moduli and their applications to the forms $x^{m} - 2^{n}$ and $x^{2} - F_{3 n} /2$

Ke-Jian Wu, Zhi-Wei Sun

In this paper we construct a cover {a_s(mod n_s)}_{s=1}^k of Z with odd moduli such that there are distinct primes p_1,...,p_k dividing 2^{n_1}-1,...,2^{n_k}-1 respectively. Using…
