Real-world networks may exhibit a detachment phenomenon determined by the canceling of previously existing connections. We discuss a tractable extension of the Yule model to account for this feature. Analytical results are derived and discussed both asymptotically and for a finite number of links. Comparison with the original model is performed in the supercritical case. The first-order asymptotic tail behavior of the two models is similar but differences arise in the second-order term. We… 
Generalized Nonlinear Yule Models
With the aim of considering models related to random graphs growth exhibiting persistent memory, we propose a fractional nonlinear modification of the classical Yule model often studied in the
Uniform Preferential Selection Model for Generating Scale-free Networks
This paper proposes a model that describes the degree distribution for the whole range of k > 0, i.e., before and after k m i n and demonstrates that the degree distributions of the graphs generated by this model match well with those of the real-world graphs.
Analysis of a Model for Generating Weakly Scale-free Networks
This paper proposes a model that describes this particular degree distribution for the whole range of $k>0$ and performs comprehensive mathematical analysis of the model in the discrete domain and compares the degree distribution generated by these models with that of real-world networks.
Generating Graphs by Creating Associative and Random Links Between Existing Nodes
This paper proposes a new generative model for generating realistic networks that is a blend of three key ideas namely preferential attachment, associativity of social links and randomness in real networks and gives both qualitative and quantitative results for clarity.
Random Graphs Associated to Some Discrete and Continuous Time Preferential Attachment Models
We give a common description of Simon, Barabási–Albert, II-PA and Price growth models, by introducing suitable random graph processes with preferential attachment mechanisms. Through the II-PA model,

We extend the classical one-parameter Yule-Simon law to a version depending on two parameters, which in part appeared in Bertoin [2019] in the context of a preferential attachment algorithm with


Multifractal properties of growing networks
We introduce a new family of models for growing networks. In these networks new edges are preferentially attached to vertices with a higher number of connections, and new vertices are created by
Degree distributions of evolving networks
In this paper, we propose a simple evolving network model with link and node removals as well as additions and show that this evolving network is scale free with a degree exponent varying in (1,4]
Emergence of scaling in random networks
A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.
Evolution of networks
The recent rapid progress in the statistical physics of evolving networks is reviewed, and how growing networks self-organize into scale-free structures is discussed, and the role of the mechanism of preferential linking is investigated.

  • 2001
A simple and elegant model for scaling phenomena in general copy- and growth-processes as proposed by Simon in 1955 is recalled and when combined with an experimental measurement of network growth in the World Wide Web, this classical model is able to model the in-link dynamics and predicts the scaling exponent gamma=2.1 in accordance with observation.
Scale-Free Networks: A Decade and Beyond
An avalanche of research has shown that many real networks, independent of their age, function, and scope, converge to similar architectures, a universality that allowed researchers from different disciplines to embrace network theory as a common paradigm.

Theory of Zipf's Law and Beyond
Zipf's law is one of the few quantitative reproducible regularities found in economics. It states that, for most countries, the size distributions of city sizes and of firms are power laws with a
