Exponential bounds for noncommuting systems of matrices Brian Jefferies (2001) Studia Mathematica It is shown that a finite system T of matrices whose real linear combinations have real spectrum satisfies a bound of the form | | e i ⟨ T , ζ ⟩ | | ≤ C ( 1 + | ζ | ) s e r | ℑ ζ | . The proof appeals to the monogenic functional calculus.
