On Linear Maps Preserving Spectrum, Spectral Radius and Essential Spectral Radius

open access: yes, 2016
In this thesis, we focus our study on a part of the linear maps on algebras of operators that preserve certain properties of operators. We study linear maps preserving spectrum. Let X and Y be Banach spaces. We show that a spectrum preserving surjective linear map ϕ from B(X) to B(Y) is either of the form ϕ(T) = ATA-1 for an isomorphism A of X onto Y ...
