2×2上三角算子矩阵的A-Weyl定理的稳定性
Stability of A-Weyl's Theorem for 2 × 2 Upper Triangular Operator Matrices
摘要
Abstract
We considered A-Brow der's theorem and A-Weyl's theorem of Weyl theorem .By using the topological uniform descent method ,we obtained a new equivalent condition and decision method for arbitrary C∈ B( H ) ,operator MC satisfying A-Brow der's theorem and the A-Weyl's theorem under small compact perturbations .关键词
