Resumen: | Let 饾憞 be a bounded linear operator acting on a Banach space X such that 饾憞 or 饾憞* has the SVEP. We prove that the spectral mapping theorem holds for the semi-essential approximate point spectrum 饾湈鈧汼BF卤 + (饾憞); and we show that generalized a-Browder鈥檚 theorem holds for 茠(饾憞) for every analytic function 茠 defined on an open neighbourhood 饾殑 of 饾湈(饾憞): Moreover, we give a necessary and sufficient condition for such 饾憞 to obey generalized a-Weyl鈥檚 theorem. An application is given for an important class of Banach space operators. |
