Abstract
The main purpose of the paper is to investigate the spectra of the Cesàro operator Cq, where on Banach spaces. For the method of the proof is to exhibit a relationship between the operator Cq and a generalized difference operator Δab. Furthermore, for it is shown that the operator Cq is compact on certain Banach spaces. In this case, the spectra of Cq are completely determined.

摘要
本文的主要目的是研究光谱 Cesàro 算子C q,其中在巴拿赫空间上。为了证明的方法是展示算子C q和广义差分算子Δ ab之间的关系。此外,对于结果表明,算子C q在某些Banach 空间上是紧的。在这种情况下,C q的光谱完全确定。
