A Projection Characterization and Symmetry Bootstrap for Elements of a von Neumann Algebra that are Nearby Commuting Elements

David Herrera

We define a symmetry map $\ddot{I}†$ on a unital $C^{\ast }$-algebra $\mathcal{A}$ to be an $\mathbb{R}$-linear map on $\mathcal{A}$ that generalizes transformations on matrices like: transpos…
