A proof of the Corrected Beiter conjecture

Jia Zhao, Xianke Zhang

We say that a cyclotomic polynomial Φ_{n}(x) has order three if n is the product of three distinct primes, p<q<r. Let A(n) be the largest absolute value of a coefficient of Φ_{n}(x…

On the coefficients of the cyclotomic polynomials of order three

Jia Zhao, Xianke Zhang

We say that a cyclotomic polynomial Phi_{n}(x) has order three if n is the product of three distinct primes, p<q<r. Let A(n) be the largest absolute value of a coefficient of Phi_{…

Elliptic curves of twin-primes over Gauss field and Diophantine Equations

DeRong Qiu, Xianke Zhang

Let be twin prime numbers with . Consider the elliptic curves E=E_σ: y^2 = x (x+σp)(x+σq) . (σ=\pm 1). E=E_σis also denoted as E_+ or E_- when σ= +1or $-1.Here the M…
