闭算子 meaning in English

[数学] closed operator

In this paper , we discusse the stability of perturtation of m - p inverses of closed operator function and then the stability of least square solution of elliptic partial differential equations of second order with unbounded coefficients
本文讨论了闭算子的m - p广义逆的扰动,并由此讨论首项系数本质无界的二阶散度型椭圆型微分方程的最小范数极小二乘解的稳定性
We prove that m has property ( p ) if and only if ( 11 ) let m be as in ( 10 ) then m and every weakly closed subspace including m have proverty ( p ) if and only if for any t b ( h } , there exist x , y h . such that ( 12 ) let a be a completely distributive subspace lattice algebra acting on a hilbert space , then the rank one subalgebra of a is dense in a if and only if , the weak closures of the first and the second preannihilators of a in the space of all trace class operators are reflexive
一弱闭算子空间，称州具有性质( p ) ，如果州中秩一算子生成的子空间在期中a一弱稠密.我们证得:川具有性质( p ) ，等价于州: = { t丁扭) : tx任[州上习， z任火} . ( ll )设川如( l0 )所述，则川以及包含川的每个a一弱闭子空间都具有性质( p ) ，当且仅当，对任意t任侧哟，都存在x ，，任火使得t一x y州
