对于∏1空间上J-yon Neumann代数的导子进行了讨论,给出了∏1空间上交换J-von Neumann代数的导子均是内导子的充要条件,对于一般情形,指出:∏1空间Ⅰ类,Ⅱb类的J—yon Neumann代数均存在外导子,对于Ⅲb类的J—von Neumann的导子也进行了讨论.
The author discussed the derivation of J-von Neumann algebra in ∏1, pointed out that every derivation of commutative J-von Neumann algebra in ∏1 is inner if and only if the critical points of J-self-adjoint operators are complete regular critical points. To non-commutative J-yon Neumann algebra, it is showed that there exists outer derivation in any non-commutative J-von Neumann algebra of the class I, Ⅱb. Meanwhile, the author discussed the derivation of J-yon Neumann algebra of the class Ⅲb.
