Notations.

The set of non-negative integer numbers, integer numbers and rational numbers are denoted respectively $ \mathbb {N}$, $ \mathbb {Z}$ and $ \mathbb {Q}$, as usual. For an integer n $ \in$ $ \mbox{${\mathbb Z}$}$ the set of the multiples of n (all of them: positive, null or negative) is denoted by n$ \mbox{${\mathbb Z}$}$. For an integer n $ \in$ $ \mbox{${\mathbb Z}$}$ the residue class ring of the binary relation (a, b) $ \longmapsto$ a $ \equiv$ b modn is denoted by $ \mbox{${\mathbb Z}$}$/n$ \mbox{${\mathbb Z}$}$, as usual. For a ring $ \mathbb {A}$, we denote by $ \mbox{${\mathbb A}$}$[x] the ring of univariate polynomials in x with coefficients in $ \mathbb {A}$.
