Characterizations of the semi-harmonious and harmonious quasi-projection pairs on Hilbert $C^{*}$ -modules

Xiaoyi Tian, Qingxiang Xu, Chunhong Fu

For each adjointable idempotent $Q$ on a Hilbert $C^{*}$ -module $H$ , a specific projection $m (Q)$ called the matched projection of $Q$ was introduced recently due to the characteriza…

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…
