摘要：
In this article we study left and right poles of the resolvent of a bounded operator defined on an infinite-dimensional complex Banach space. In particular, some spectral decompositions associated with left and right poles of the resolvent are established, and the components of the upper and lower semi B-Fredholm regions are studied by means of the localized single valued extension property.
