Some Conditions Under Which Jordan Derivations Are Zero
Publication date: Available online 24 September 2016 Source:Journal of Taibah University for Science Author(s): Z. Jokar, A. Hosseini, A. Niknam In the current article, we obtain the following results: Let A be an algebra and P be a semi-prime ideal of A . Suppose that d : A → A P is a Jordan derivation such that dim { d ( a ) | a ∈ A } ≤ 1 . If d ( P ) = { 0 } , then d is zero. As an application of this result, we prove that if A is an algebra such that ⋂ P ∈ Σ ( A ) P = { 0 } , where Σ ( A ) denotes the set of all semi-prime ideals of A , and further each semi-prime ideal of A is of codimension 1, the...
