Abstract :
Let T be a bounded linear operator acting on a Banach space X such that T or its adjoint T ∗ has the
single-valued extension property. We prove that the spectral mapping theorem holds for the B-Weyl spectrum,
and we show that generalized Browder’s theorem holds for f (T ) for every analytic function f defined
on an open neighborhood U of σ(T ). Moreover, we give necessary and sufficient conditions for such T to
satisfy generalized Weyl’s theorem. Some applications are also given.
