Group Degree Centrality and Centralization in Networks [PDF]
Mathematics, 2020 The importance of individuals and groups in networks is modeled by various centrality measures. Additionally, Freeman’s centralization is a way to normalize any given centrality or group centrality measure, which enables us to compare individuals or groups from different networks. In this paper, we focus on degree-based measures of group centrality and

The B.E. Journal of Theoretical Economics, 2017 AbstractWe establish a relationship between decay centrality and two widely used measures of centrality, namely degree and closeness. We show that for low values of the decay parameter the nodes with maximum decay centrality also have maximum degree, whereas for high values of the decay parameter they also maximize closeness.

Internet Mathematics, 2014 Given a social network, which of its nodes are more central? This question has been asked many times in sociology, psychology and computer science, and a whole plethora of centrality measures (a.k.a. centrality indices, or rankings) were proposed to account for the importance of the nodes of a network.

Journal of Computational Geometry, 2015 An important task in trajectory analysis is clustering. The results of a clustering are often summarized by a single representative trajectory and an associated size of each cluster. We study the problem of computing a suitable representative of a set of similar trajectories.

Central Place and Central Flow
eTopoi. Journal for Ancient Studies, 2020 This chapter presents the idea of integrating central place and central flow theory in order to gain a deeper understanding of economic interactions, ranging from the local to the supra-regional scale. Central place theory is suitable to describe the local exchange relation-ships between settlements and their hinterland.
