摘要：
Necessary and sufficient conditions are provided under which the weighted Moore-Penrose inverse A(MN)(dagger) exists, where A is an adjointable operator between Hilbert C*-modules, and the weights M and N are only self-adjoint and invertible. Relationship between weighted Moore-Penrose inverses A(MN)(dagger) is clarified when A is fixed, whereas M and N are variable. Perturbation analysis for the weighted Moore-Penrose inverse is also provided.
