چكيده فارسي :
A Banach space T∈ B(X) is {M^*}-paranormal operators. {M^*}-paranormal operators have SVEP. It is proved that {T^*}∈ B(X) has the single-valued extension property and T is transaloid , then a-Weyl s theorem holds for f(T) for
(( every f∈ H (sigma (T
.It is also proved that if {T^*} has the single-valued extension property , then the spectral mapping theorem holds for the Weyl s spectrum and for the essential approximate point spectrum
