Ideals and Higher Derivations in Commutative Rings

Canadian Journal of Mathematics, 1972
In this paper, we wish to generalize the following lemma first proven by O. Zariski [5, Lemma 4]. Let O be a complete local ring containing the rational numbers and let m denote the maximal ideal of O. Assume there exists a derivation δ of O such that δ(x) is a unit in O for some x in m.

\(\Phi\)-derivations and commutativity of rings and algebras

2022
Summary: The main purpose of this paper is to investigate the effect of \(\Phi \)-derivatives on the commutativity of rings and algebras. Let \(\mathfrak{R}\) be a 2-torsion free prime ring, \(d: \mathfrak{R} \rightarrow \mathfrak{R}\) be a \(\Phi\)-derivation such that \(\Phi\) is an epimorphism and \(d\Phi = \Phi d = d\). If \([\Phi (a), \Phi (x)]d(y)
