Research output: Contribution to journalArticle


Let B be a ring with identity 1, D a derivation of B, and B[X; D] the skew polynomial ring such that αX = Xα + D(α) for each a S B. Assume that B is a ring of prime characteristic p. Let f = Xp -Xa -b ∈ B[X; D] such that f B[X; D] = B[X; D] f. We study separability and H-separablity of f.
