Abstract
We give necessary and sufficient conditions for a Banach space operator with the single valued extension property (SVEP) to satisfy Weyl's theorem and -Weyl's theorem. We show that if or has SVEP and is transaloid, then Weyl's theorem holds for for every . When has SVEP, is transaloid and is -isoloid, then -Weyl's theorem holds for for every . We also prove that if or has SVEP, then the spectral mapping theorem holds for the Weyl spectrum and for the essential approximate point spectrum.
