On colorings of graph powers

open access: yesDiscrete Mathematics, 2009
In this paper, some results concerning the colorings of graph powers are presented. The notion of helical graphs is introduced. We show that such graphs are hom-universal with respect to high odd-girth graphs whose $(2t+1)$st power is bounded by a Kneser graph. Also, we consider the problem of existence of homomorphism to odd cycles. We prove that such

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

open access: yesDiscrete 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]

open access: yes, 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.
