Abstract
Let T be an algebraically paranormal operator acting on Hilbert space. We prove : (i) Weyl’s theorem holds for f(T) for every f $\in$ H(σ(T)); (ii) a-Browder’s theorem holds for f(S) for every S $\prec$ T and f $\in$ H(σ(S)); (iii) the spectral mapping theorem holds for the Weyl spectrum of T and for the essential approximate point spectrum of T.
