In this paper, we show that if T is p-ω-hyponormal, the nonzero points of the approximate and joint approximate point s......

对于复Hilbert空间上的正常算子 ,当H是可分的空间时 ,与其相关的广义特征函数展开形式为f =limn→∞a→∞ nj=1 ∫{ ｜z｜ a} ∩Mj(U......

令T是以{Wk}∞k=1(Ω)(B)((An)")为权序列的内射算子权移位.设T是强不可约的,而且sup 1≤k≤∞‖Wk-1‖＜+∞.用(A)′(T)表示T的换位......

In this paper, we introduce the concept of weakly reducible maximal triangular algebras φwhich form a large class of ma......
