Add to ORKGAbstract. The aim of this paper is to study the Weyl type-theorems for the orthogonal direct sum S T, where S and T are bounded linear operators acting on a Banach space X. Among other results, we prove that if both T and S possesses property (gb) and if (T) a(S), (S) a(T), then ST possesses property (gb) if and only if SBF+ (ST) = SBF
