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…

$C^{}$ -isomorphisms associated with two projections on a Hilbert $C^{}$ -module

Chunhong Fu, Qingxiang Xu, Guanjie Yan

Motivated by two norm equations used to characterize the Friedrichs angle, this paper studies $C^{*}$ -isomorphisms associated with two projections by introducing the matched triple a…
