Identities with Engel conditions on derivations

open access: yesMonatshefte für Mathematik, 2010
Let \(R\) be a semiprime ring with center \(Z(R)\), symmetric Martindale quotient ring \(Q\), and nonzero derivation \(D\). The authors prove two results involving \(D\) and Engel conditions. Let \([x,y_1]_1=xy_1-y_1x\) and for \(n>1\) set \([x,y_1,\dots,y_n]_n=[[x,y_1,\dots,y_{n-1}]_{n-1},y_n]_1\).
