摘要
Let X, Y be Banach spaces, R: X -> Y and S: Y -> X be bounded linear operators. When lambda not equal 0, we investigate common properties of lambda I - SR and lambda I - RS. This work should be viewed as a continuation of researches of Barnes and Lin et al.. We also apply these results obtained to B-Fredholm theory, extensions and Aluthge transforms.
