In this project, we will study the following several problems:.1) Suppose that A is a unital, simple, real rank zero C*-algebra. Must the linear span of the projections coincide with A?.2) Suppose that A is a unital, simple, amenable C*-algebra. Is the linear span of the projections in A closed in the norm topology?.3) Is every 2-local derivation on a general C*-algebra a derivation?.4) 2-local derivations on some subspace lattice algebras, such as Nest algebras, CSL algebras and so on..5) Is every weak-2-local derivation on an arbitrary von Neumann algebra a derivation?
本课题我们将研究以下几个问题:.1) 设A是单的有单位的实秩零的C*-代数. 则A是否由A中的投影线性生成?.2) 设A是单的有单位的顺从的C*-代数. 则由A中的投影全体线性生成的子空间在A中是否是范数闭的?.3) 任意C*-代数上的2-局部导子是否都是导子?.4) Nest代数、CSL代数等一些子空间代数上的2-局部导子问题..5) 任意von Neumann代数上的弱-2-局部导子是否都是导子?
算子代数是泛函分析的重要分支,对它的2-局部导子研究是近期的热点课题。我们围绕2-局部导 子与相关的算子理论算子代数问题及其应用方面展开了多方面的研究工作,取得了重要的进展。证明了I型的C*-代数上的2-局部导子都是导子,对一类非I型的C*-代、及群代数和一些非自伴的代数也获得了相应的结果;也研究了具体的函数空间上算子理论算子代数,证明了Bergman投影的算子性质,给出了Lp-Lq的有界性问题、紧性问题的完整性刻画;借助泛函分析的工具证明了J-自伴型的行列式点过程的中心极限定理是成立的。
