Central *-Differential Identities in Prime Rings
Published online by Cambridge University Press: 20 November 2018
Abstract
Let R be a prime ring with involution and d, δ be derivations on R. Suppose that xd(x)—δ(x)x is central for all symmetric x or for all skew x. Then d = δ = 0 unless R is a commutative integral domain or an order of a 4-dimensional central simple algebra.
