Birkhoff-James Orthogonality and Its Pointwise Symmetry in Some Function Spaces

Functional Analysis 2022-05-27 v1

Abstract

We study Birkhoff-James orthogonality and its pointwise symmetry in commutative CC^* algebras, i.e., the space of all continuous functions defined on a locally compact Hausdorff space that vanish at infinity. We use this characterization to obtain the characterization of Birkhoff-James orthogonality on LL_\infty space defined on any arbitrary measure space. We also do the same for the LpL_p spaces for 1p<1\leq p<\infty.
