The minus order for idempotents

Yuan Li, Jiajia Niu, Xiaoming Xu

Let $P$ and $Q$ be idempotents on a Hilbert space $H .$ The minus order $P ⪯ Q$ is defined by the equation $P Q = QP = P .$ In this note, we first present some necessary an…

The structures and decompositions of symmetries involving idempotents

Yuan Li, Jiaxin Zhang, Nana Wei

Let $H$ be a separable Hilbert space and $P$ be an idempotent on $H .$ We denote by $Γ_{P} = {J : J = J^{*} = J^{- 1} and J P J = I - P}$ and $…
