Original abstract

Let $D\in Z$ and $C_D := \{f(x) = x^3 + ax^2 + b^x + c\in Z[x];D_f = D\}$ where $D_f$ is the discriminant of $f(x)$. Assume that $D < 0$, $D$ is square-free, $3\nmid D$, and $3 \nmid h(-3D)$ where $h(-3D)$ is the class number of $Q(\sqrt -3D)$. We prove that all polynomials in $C_D$ have the same type of factorization over any Galois field $ F_p$, $p$ being a prime, $p > 3$.
