Abstract:

A bounded linear operator defined on a Hilbert space a sufficient and necessary condition is established for which Browder’s theorem and Weyl’s theorem hold by means of the new spectrum σ1( · ). Meanwhile,  the relations of Weyl type theorem are studied.

Key words: operators with consistency in Fredholm; Browder’s theorem;  Weyl’s theorem; spectrum
