Relative perturbation bounds for generalized nonnegative and positive polar factors，李寒宇，Hu Yang，The changes in the generalized nonnegative and positive polar factors of weighted polar decomposition are studied under the additive perturbation. Some re
Relative perturbation bounds for weighted polar decomposition，李寒宇，杨虎，In this paper, we obtain the relative perturbation bounds for
weighted unitary polar factor of the weighted polar decomposition in the weighted unitarily invariant norm, weighted
