摘要 讨论了算子的广义Kato分解与拓扑一致降指数,给出算子既有广义Kato分解又有拓扑一致降指数的等价刻画,并由此对算子谱精细结构进行进一步的细化. We discuss the generalized Kato decomposition and the topological uniform descent of an operator. We give a characterization of an operator which both admits a generalized Kato decomposition and has topological uniform descent. By means of this result, we obtain a new spectral structural diagram of an operator.
