Divisibility on point counting over finite Witt rings

Wei Cao, Daqing Wan

Let $F_{q}$ denote the finite field of $q$ elements with characteristic $p$ . Let $Z_{q}$ denote the unramified extension of the $p$ -adic integers $Z_{p}$ with…

Notes On a Borwein and Choi's conjecture of cyclotomic polynomials with coefficients $\pm 1$

Shaofang Hong, Wei Cao

Borwein and Choi conjectured that a polynomial $P (x)$ with coefficients $\pm 1$ of degree $N - 1$ is cyclotomic iff $$P(x)=\pm Φ_{p_1}(\pm x)Φ_{p_2}(\pm x^{p_1})\cdots Φ_{p_r}(\pm x^{…

Normal bases and irreducible polynomials

Hua Huang, Shanmeng Han, Wei Cao

Let $F_{q}$ denote the finite field of $q$ elements and $F_{q^{n}}$ the degree $n$ extension of $F_{q}$ . A normal basis of $F_{q^{n}}$ over $\mathbb{F}…
