Abstract:In this note we show that if either T or T* is totally *-paranormal then Weylrsquos theorem holds for f(T) for every f $$ \in H (\sigma (T)) $$ , and also a-Weylrsquos theorem holds for f(T) if T is totally *-paranormal. We prove that if either T or T* is *-paranormal then the spectral mapping theorem holds for the Weyl spectrum and for the essential approximate point spectrum.
