In this note, we study one of the main outcomes of the Russo-Dye Theorem of JB*-algebra: a linear operator that preserves Brown-Pedersen-quasi invertible elements between two JB*-algebras is…
The main goal of this paper is to introduce and explore
In this article, we survey a geometric property, called Bade-property, originally introduced by William Bade. First, we review Bade’s work in normed linear spaces. Next, we illustrate various…
