主要研究了压缩的*-仿正规算子的一些性质,证明了若T是一个压缩的*-仿正规算子,则正算子D=1/2(T^*2T^2-2TT^*+I)是一个压缩算子,且算子序列{D^n}强收敛于一个投影算子P,满足T^*P=0;若T没有非平凡的不变子空间,则(i)T是真压缩算子,(ii)正算子D=1/2(|T^2|-2|T^*|^2+I)是强稳定压缩算子.
In this paper, we mainly prove some properties of contraction *-paranormal operators. If T is a contraction of * -paranormal operators, firstly we show that the nonnegative operator D=1/2(T^*2T^2-2TT^*+I) is a contraction whose power sequence {D^*} converges strongly to a projection P, and T^* P=0; secondly, we show if T has no nontrivial invariant subspace, then (i) T is a proper contraction, (ii) the nonnegative operator D=1/2(T^*2T^2-2TT^*+I) is a strongly stable contraction.
