    abstract = {Let, R be a ring and σ is an endomorphism for
R. With multiplication rule xa = σ(a)x for all a∈R, the set
of polynomials a<sub>0</sub>+a<sub>1</sub>x+, ..., +a<sub>n</sub>x<sup>n</sup> where a<sub>i</sub>&isin;R, forms a
ring. The ring is called skew polynomial ring. This ring is
non-commutative due to the multiplication rule.}
