Let \(\mathcal{H}\) be a Hilbert space, and let \(K(\mathcal{H})\) be the \(C^*\)-algebra of compact operators on \(\mathcal{H}\). In this paper, we present some characterizations of the norm-parallelism for elements of a Hilbert \(K(\mathcal{H})\)-module by employing the Birkhoff--James orthogonality. Among other things, we present a characterization of transitive relation of the... Show more
