He was very active in my class, was quick to understand new knowledge, answered my questions promptly, and was especially good at solving problems that require rather strong logical thinking ability and fundamental knowledge. What's instructed in the Abstract Algebra course is theoretical and abstract so that a lot of students thought it's tough for them to learn. Only Mr.

他课堂表现积极，对新知识吸收消化非常快，能迅速对我提出的问题做出反应，对解决那些逻辑性比较强的以及需要运用基础知识解决的问题尤其擅长，在抽象代数课上，讲授的都是一些概念化和抽象化的内容，学生普遍反映学习起来比较困难，只有Mr。

We show that Jordan multiplicative bijective maps on prime operator algebrasmust be additive. As its application, we show that every Jordan * multiplicative bijec-tive map on every factor C~* algebra is a C~* isomorphism or a conjugate C~* isomorphism,in the special case of B, it must be a *-isomorphism or a conjugate *-isomorphism.We also prove the additivity of Jordan multiplicative bijective maps on nest algebras.

证明了素算子代数上Jordan可乘双射的可加性，利用这一结论刻画了因子C~*代数上的Jordan*可乘双射，我们的结果表明这样的映射一定是C~*同构或共轭C~*同构；证明了套代数上的Jordan可乘双射的可加性。
