Benhida, C.; Zerouali, E. H.; Zguitti, H. Spectral properties of upper triangular block operators. (English) Zbl 1105.47005 Acta Sci. Math. 71, No. 3-4, 681-690 (2005). Summary: We describe local spectral properties of upper triangular block operators having a diagonal that satisfies the single valued extension property together with its adjoint. Some results on \(n\)-normal operators and Jordan operators are recaptured.
