Abstract
In this article, we study the intersection relations of the components of approximate point spectrum σa(T) with σa (S) and σs (S), T and S being quasisimilar operators acting on a Banach space. First, we give the necessary and sufficient conditions for the component of σa(T) to intersect σa(S). Secondly, we prove that every component of σa(T) intersects σs(S), and every component of σs(T) intersects σa(S).关键词
