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 matched projections of idempotents on Hilbert $C^{*}$ -modules

Xiaoyi Tian, Qingxiang Xu, Chunhong Fu

The aim of this paper is to give new characterizations of some fundamental issues about idempotents. In the general setting of adjointable operators on Hilbert $C^{*}$ -modules, a new…
