Abstract: We discuss the relation between the single-valued extension property (that is, Dunford's property (A)) and spectral manifolds $ {X_T}(F)$ of a bounded linear operator. In particular, we prove that Dunford's property (C) implies the property (A). We also prove that if $ T \in B(X)$ has the property $ ({\beta ^{\ast}})$ introduced by Fong, then $ X_{{T^{\ast}}}^{\ast}(F) = {X_T}{(\mathbb{C}\backslash F)^ \bot }$ for every closed set $ F$ in the complex plane $ \mathbb{C}$.
