Let H be an infinite dimensional complex Hilbert space and T be a bounded linear operator on H. We show that if there exists such that the closure of is H, then there is a subsequence such that the closed linear span of is not the whole space H.

关于 Hilbert 空间算子的超循环向量的注记
设H是一个无限维复数希尔伯特空间,T是H上的一个有界线性算子。我们证明如果存在 使得关闭 是H,则有子序列 使得闭合线性跨度 不是整个空间H。
