Abstract:

The objective of this research is to prove that an additive mapping T:R → R is a centralizer on R if it satisfies any one of the following identities:

for all x ∈ R, where n ≥ 1 is a fixed integer and R is any suitably torsion free semiprime ring. Some results on involution "*" are also presented as consequences of the main theorems. In addition, we will take criticism in account with examples.
