Yildirim Department of Mathematics, Faculty of Sciences, Cumhuriyet University, 58140 Sivas, Turkey Journal Article 2010 04 25 There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are<br />motivated by applications to physics (in particular, quantum mechanics). In this study, the relationship between<br />the subdivisions of spectrum which are not required to be disjoint and Goldberg's classification are given.<br />Moreover, these subdivisions for some summability methods are studied. https://ijsts.shirazu.ac.ir/article_2140_19461ed8a7a9811825fdac2d5d4a7ba2.pdf
