2~*2上三角算子矩阵的谱的填洞问题
The Filling Holes Problems of Operator Spectra of 2~*2 Upper Triangular Operator Matrices
【摘要】 设Mc=A C0 B∈B(X Y)为定义在Banach空间X Y上的上三角算子矩阵.讨论了Mc的左(右)谱σl(σr),左(右)本性谱σle(σre)和本性谱σe的填洞问题.
【Abstract】 Let Mc=AC0B∈B(XY) be an upper triangular operator acting on the Banach space B(XY).It studies on the filling holes problems of various special operator spectra of Mc including five cases such as left spectra,right spectra,left essential spectra,right essential speatra and essential spectra.
