Ulam stability for some classes of C*-algebras
McKenney, Paul · Vignati, Alessandro
Original · EN
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→ B is approximately a *-homomorphism then there is an actual *-homomorphism close to ϕ by a factor depending only on how far is ϕ from being a *-homomorphism and not on A or B.
