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.http://ijsts.shirazu.ac.ir/article_2140_19461ed8a7a9811825fdac2d5d4a7ba2.pdf
