A generalization of the Roberts orthogonality: from normed linear spaces to c∗ -algebras

  • Authors: Faryad E., Khurana D., Moslehian M.S., Sain D.
    Year: 2023 | IIM Ranchi
    Source: Monatshefte fur Mathematik
    DOI: 10.1007/s00605-022-01799-7

We introduce and study an extension of the Roberts orthogonality, in the setting of C∗-algebras. More precisely, in a C∗-algebra A, for a, b∈ A and a nonempty subset of A, say B, a is called B-Roberts orthogonal to b, denoted by a⊥RBb, if ‖ a+ bc‖ = ‖ a- bc‖ for all c∈ B. For certa...(Read Full Abstract)

A study of local symmetry of Birkhoff–James orthogonality in Banach spaces

We present a complete characterization of the right-symmetric points in the one sum of two Banach spaces. We also obtain some basic properties of the left-symmetric (right-symmetric) points in the p sum, (Formula presented.) ((Formula presented.)), of two Banach spaces. Using these properties we (a)...(Read Full Abstract)
