摘要
. 给出了加权Moore-Penrose逆A†MN存在的充分必要条件,其中A是Hilbert C * -模之间的可合算子,且权M和权N仅自伴且可逆。当A固定时,明确了加权Moore-Penrose逆A†MN之间的关系,而M和N是可变的。给出了加权Moore-Penrose逆的摄动分析。
WEIGHTED MOORE-PENROSE INVERSES OF ADJOINTABLE OPERATORS ON INDEFINITE INNER-PRODUCT SPACES
. Necessary and sufficient conditions are provided under which the weighted Moore–Penrose inverse A † MN exists, where A is an ad- jointable 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 is clarified when A is fixed, whereas M and N are variable. Perturbation analysis for the weighted Moore–Penrose inverse is also provided.
