AB与BA正则性谱之间的关系
Relationships of the Spectrum of Regularity between Operators AB and BA
摘要
Abstract
Study the relationships of the spectrum of regularity between the operators AB and BA , showing that σRi(AB)\{O} = σR, (BA)\{0} , where i = 1,… ,15 . Under the condition that A,B are injective, also obtain that σR3(AB) = σR3(BA) .关键词
