The minimal and maximal symmetries for $J$ -contractive projections

Yuan Li, Xiaomei Cai, Jiajia Niu +1

In this paper, we firstly character the structures of symmetries $J$ such that a projection $P$ is $J$ -contractive. Then the minimal and maximal elements of the symmetries $J$ with…

The absolute values and support projections for a class of operator matrices involving idempotents

Yuan Li, Xiaomei Cai, Shuaijie Wang

Let $λ \in R,$ $μ \in R$ and $B$ be a linear bounded operator from a Hilbert space $K$ into another Hilbert space $H .$ In this paper, we conside…
