Abstract
Let a Banach space and a bounded linear operator on We denote by the set of all such that does not have the single-valued extension property at . In this note we prove equality up to between the left Drazin spectrum and the left B-Fredholm spectrum and between the semi-essential approximate point spectrum and the left Drazin spectrum. As applications we investigate generalized Weyl's theorem for operator matrices and multipliers operators.
