The Frobenious distances from projections to an idempotent matrix

Xiaoyi Tian, Qingxiang Xu, Chunhong Fu

For each pair of matrices $A$ and $B$ with the same order, let $∥ A - B ∥_{F}$ denote their Frobenius distance. This paper deals mainly with the Frobenius distances from projections to…

The generalized polar decomposition, the weak complementarity and the parallel sum for adjointable operators on Hilbert $C^{*}$ -modules

Xiaofeng Zhang, Xiaoyi Tian, Qingxiang Xu

This paper deals mainly with some aspects of the adjointable operators on Hilbert $C^{*}$ -modules. A new tool called the generalized polar decomposition for each adjointable operator…
