Weak multiplicative operators on function algebras without units

Thomas Tonev — 2010

Banach Center Publications

For a function algebra A let ∂A be the Shilov boundary, δA the Choquet boundary, p(A) the set of p-points, and |A| = |f|: f ∈ A. Let X and Y be locally compact Hausdorff spaces and A ⊂ C(X) and B ⊂ C(Y) be dense subalgebras of function algebras without units, such that X = ∂A, Y = ∂B and p(A) = δA, p(B) = δB. We show that if Φ: |A| → |B| is an increasing bijection which is sup-norm-multiplicative, i.e. ||Φ(|f|)Φ(|g|)|| = ||fg||, f,g ∈ A, then there is a homeomorphism ψ: p(B) → p(A) with respect...

Algebra isomorphisms between standard operator algebras

Thomas TonevAaron Luttman — 2009

Studia Mathematica

If X and Y are Banach spaces, then subalgebras ⊂ B(X) and ⊂ B(Y), not necessarily unital nor complete, are called standard operator algebras if they contain all finite rank operators on X and Y respectively. The peripheral spectrum of A ∈ is the set σ π ( A ) = λ σ ( A ) : | λ | = m a x z σ ( A ) | z | of spectral values of A of maximum modulus, and a map φ: → is called peripherally-multiplicative if it satisfies the equation σ π ( φ ( A ) φ ( B ) ) = σ π ( A B ) for all A,B ∈ . We show that any peripherally-multiplicative and surjective map φ: → , neither assumed to be linear nor...
