Digraph代数上的2-局部导子

2-Local Derivations on Digraph Algebras

导出

摘要本文证明了对称digraph代数上的每一个2-局部导子都是导子,并给出一个例子说明该结论在非对称digraph代数上不成立． In this paper, we prove that every .2-local derivation from any symmetric digraph algebra into itself is a derivation. Moreover, we give an example to show that the conclusion may not be true if it has not the condition of symmetry.
