Abstract
This paper is devoted to the study of dominant operators with an emphasis on their spectral properties. In particular the equation (T−λ)f(λ)≡ ≡x (T a dominant or hyponormal operator on the Hilbert space ℌ,x∈ℌ andf a function from the open setU to ℌ) is investigated in an effort to discover necessary and/or sufficient conditions for the analyticity off.
