Some New Results Concerning Power Graphs and Enhanced Power Graphs of Groups

Discrete Applied Mathematics
Theorem 4.4 of the first version of the manuscript turned out to be incorrect, which we show in the present version by providing a counterexample. Therefore, Theorem 4.4 and Corollary 4.5 of the first version have been removed. Further, Theorems 4.8 and 4.9 have been added.

Drawing Power Law Graphs [PDF]

, 2005
We present methods for drawing graphs that arise in various information networks. It has been noted that many realistic graphs have a power law degree distribution and exhibit the small world phenomenon. Our methods are influenced by recent developments in the modeling of such graphs.

Bounding the bias of tree-like sampling in IP topologies

Networks and Heterogeneous Media, 2008
It is widely believed that the Internet's AS-graph degree distribution obeys a power-law form. However, it was recently argued that since Internet data is collected in a tree-like fashion, it only produces a sample of the degree distribution, and ...
