2-Local derivations on matrix algebras over commutative regular algebras
摘要:
本文致力于研究交换正则代数上矩阵代数的2-局部导子。本文给出了交换正则代数上允许2-局部导子不是导子的充要条件。证明了交换正则代数上的矩阵代数上的2-局部导子是导子。我们将这些结果应用于2-局部导子代数的可测和局部可测的运营商隶属于第一类冯诺依曼代数。
英文摘要:
The paper is devoted to 2-local derivations on matrix algebras over commutative regular algebras. We give necessary and sufficient conditions on a commutative regular algebra to admit 2-local derivations which are not derivations. We prove that every 2-local derivation on a matrix algebra over a commutative regular algebra is a derivation. We apply these results to 2-local derivations on algebras of measurable and locally measurable operators affiliated with type I von Neumann algebras.
