The rich-club concept has been introduced in order to characterize the presence of a cohort of nodes with a large number of links (rich nodes) that tend to be well connected between each other, creating a tight group (club). Rich-clubness defines the extent to which a network displays a topological organization characterized by the presence of a node rich-club. It is crucial for the investigati...

Recently, some convergent results of the generalized AOR iterative (GAOR) method for solving linear systems with strictly diagonally dominant matrices are presented in [Darvishi, M.T., Hessari, P.: On convergence of the generalized AOR method for linear systems with diagonally dominant cofficient matrices. Appl. Math. Comput. 176, 128-133 (2006)] and [Tian, G.X., Huang, T.Z., Cui, S.Y.: Converg...

There are differences in resource endowments, environmental regulations, and production functional areas among different regions China, which makes dairy farming have certain heterogeneity imbalance pollution control, is mainly reflected the efficiency of regions. By analyzing convergence trend environment scales, it helpful to predict potential improving efficiency, promote high-quality develo...

Most epidemiological data support the role of cl...

This paper discusses the one-city monopoly phenomenon in Turkey from 2007 to 2018 inequality. For this purpose, Theil Inequality Index is calculated for NUTS3 level, and a significant gap between İstanbul other cities obtained. Then, club convergence analysis clustering procedure are applied. According finding, overall country’s hypothesis rejected, 75 of 81 have converged into six clubs. In th...
