Shao, Chunfang The generalized inverses of the almost sharp quantum effect. (Chinese. English summary) Zbl 1240.81016 J. Shandong Univ., Nat. Sci. 46, No. 3, 99-101, 120 (2011). Summary: By using the technique of operator block, the matrix form of the almost sharp quantum effect on an infinite dimensional Hilbert space is given. Furthermore, combined with the theory of the generalized inverses, the condition of existence and the representation of the generalized inverses of the almost sharp quantum effect are studied.
