A bounded linear operator T on a normed linear space X is said to be right symmetric (left symmetric) if A ⊥B T ⇒ T ⊥B A (T⊥B A ⇒ A ⊥B T) for all A ∈ B(X), the space of all bounded linear operators on X. Turnšek [Linear Algebra Appl., 407 (2005), 189-195] proved that if X is a Hilbert space then T is right symmetric if and only if T is a scalar multiple of an isometry or coisometry. This result fails in general if the Hilbert space is replaced by a Banach space. The characterization of right and left symmetric operators on a Banach space is still open. In this paper we study the orthogonality in the sense of Birkhoff-James of bounded linear operators on (ℝn,. ∞) and characterize the right symmetric and left symmetric operators on (ℝn, .∞).
