运用算子分块的技巧,给出了无穷维希尔伯特空间H上Almost Sharp量子效应的矩阵表示形式。进一步结合广义逆理论,讨论了Almost Sharp量子效应的广义逆的存在条件及其矩阵表示。
By using the technique of operator block,the matrix form of the almost sharp quantum effect on an infinite dimensional Hilbert spaces is given.Furthermore,combined with the theory of the generalized inverses,the condition of existence and representation of the generalized inverses of the almost sharp quantum effect is studied.
