Nontrivial homeomorphisms of Čech-Stone remainders

Alessandro Vignati

We study the group of automorphisms of certain corona C*-algebras. As a corollary of a more general C*-algebraic result, we show that, under the Continuum Hypothesis, $βX\setminus…

I. Farah, B. Hart, M. Lupini +4

We begin the systematic model theoretic study of $C^{*}$ -algebras using the tools of continuous logic.

Ulam stability for some classes of C*-algebras

Paul McKenney, Alessandro Vignati

We prove some stability results for certain classes of C*-algebras. We prove that whenever $A$ is a finite-dimensional C*-algebra, $B$ is a C*-algebra and $ϕ : A \to B$ is appro…
