The dual role of friendship and antipathy relations in the marginalization of overweight children in their peer networks: The TRAILS Study. [PDF]
PLoS ONE, 2017 Weight-based stigma compromises the social networks of overweight children. To date, research on the position of overweight children in their peer network has focused only on friendship relations, and not on negative relationship dimensions.

Energy of Certain Classes of Graphs Determined by Their Laplacian Degree Product Adjacency Spectrum
Journal of Mathematics, 2022 In this study, we investigate the Laplacian degree product spectrum and corresponding energy of four families of graphs, namely, complete graphs, complete bipartite graphs, friendship graphs, and corona products of 3 and 4 cycles with a null graph.

On the domination polynomials of friendship graphs
Filomat, 2016 Let G be a simple graph of order n. The domination polynomial of G is the polynomial D(G,x)= n?i=0 d(G,i)xi, where d(G,i) is the number of dominating sets of G of size i. Let n be any positive integer and Fn be the Friendship graph with 2n + 1 vertices and 3n edges, formed by the join of K1 with nK2.

The Detection of Anomalous Users in Location-Based Social Networks by Using Graph Rules [PDF]
مدیریت مهندسی و رایانش نرم, 2022 An analysis of social networks is necessary to detect anomalous users, due to the popularity of these networks. This paper aims to detect anomalous users in location based social networks. For this purpose, an ego graph is computed for each user, and the

The Local Antimagic Chromatic Numbers of Some Join Graphs
Mathematical and Computational Applications, 2021 Let G=(V(G),E(G)) be a connected graph with n vertices and m edges. A bijection f:E(G)→{1,2,⋯,m} is an edge labeling of G. For any vertex x of G, we define ω(x)=∑e∈E(x)f(e) as the vertex label or weight of x, where E(x) is the set of edges incident to x,

Infinite generalized friendship graphs
Discrete Mathematics, 1984 Let \(\tau\geq 2\) and \(\lambda\geq 1\) be integers, and let c be an infinite cardinal number. It is shown that \(\tau \leq \lambda +1\) is necessary and sufficient for the existence of (simple) infinite graphs of order c such that every subset of \(\tau\) vertices has exactly \(\lambda\) common neighbors.
