Abstract

In this paper,a-Browder's theorem and a-Weyl's theorem for bounded linear operators are studied by means of the property of the topological uniform descent.The sufficient and necessary conditions for a bounded linear operator defined on a Hilbert space holding a-Browder's theorem and a-Weyl's theorem are established.As a consequence of the main result,the new judgements of a-Browder's theo-rem and a-Weyl's theorem for operator function are discussed.

Key words

a-Browder's theorem/a-Weyl's theorem/topological uniform descent
