对于可析πk空间上交换J-von Neumann代数谱空间的极不连通性进行了讨论,得到了可析πk空间上交换J-von Neumann代数谱空间极不连通的充要条件,并给出判断谱空间中的开集的闭包是否仍为开集的充要条件.
This paper discusses whether the spectral space of commuting J-von Neumann algebra on Pontryagian spaceπ_k is extremely disconnected space.And giving the necessary and sufficent condition that the spectral space of commuting J-von Neumann algebra on Pontryagian spaceπ_k is extremely disconnected space,meanwhile the necessary and sufficent condition is got whether the closer of open set is open set,where the closer of open set contains the degenerate eigenfunctional.
