A note on local automorphisms

Ajda Fošner (2006)

Czechoslovak Mathematical Journal

Similarity:

Let $H$ be an infinite-dimensional almost separable Hilbert space. We show that every local automorphism of $ℬ (H)$ , the algebra of all bounded linear operators on a Hilbert space $H$ , is an automorphism.

Isometries and automorphisms of the spaces of spinors.

Revista Matemática de la Universidad Complutense de Madrid

Similarity:

The relationships between the JB*-triple structure of a complex spin factor S and the structure of the Hilbert space H associated to S are discussed. Every surjective linear isometry L of S can be uniquely represented in the form L(x) = mu.U(x) for some conjugation commuting unitary operator U on H and some mu belonging to C, |mu|=1. Automorphisms of S are characterized as those linear maps (continuity not assumed) that preserve minimal tripotents in S and the orthogonality relations...

Notes on automorphisms of ultrapowers of II₁ factors

David Sherman (2009)

Studia Mathematica

Similarity:

In functional analysis, approximative properties of an object become precise in its ultrapower. We discuss this idea and its consequences for automorphisms of II₁ factors. Here are some sample results: (1) an automorphism is approximately inner if and only if its ultrapower is ℵ₀-locally inner; (2) the ultrapower of an outer automorphism is always outer; (3) for unital *-homomorphisms from a separable nuclear C*-algebra into an ultrapower of a II₁ factor, equality of the induced traces...
