Description of dynamics of stock prices by a Langevin approach
Zi-Gang Huang, Yong Chen, Yong Zhang +1
We present a time-dependent Langevin description of dynamics of stock prices. Based on a simple sliding-window algorithm, the fluctuation of stock prices is discussed in the view o…
Comment on "Maximal planar networks with large clustering coefficient and power-law degree distribution"
Zhi-Xi Wu, Xin-Jian Xu, Ying-Hai Wang
This Comment corrects the error which appeared in the calculation of the degree distribution of random apollonian networks. As a result, the expression of , which gives the p…
Does the scale-free topology favor the emergence of cooperation?
Zhi-Xi Wu, Xin-Jian Xu, Ying-Hai Wang
In a recent Letter [F.C. Santos and J. M. Pacheco Phys. Rev. Lett. \textbf{95}, 098104 (2005)], the scale-free networks are found to be advantageous for the emergence of cooperatio…
Epidemic spreading with time delay in complex networks
Xin-Jian Xu, Hai-Ou Peng, Xiao-Mei Wang +1
We present a modified \emph{susceptible-infected-susceptible} (SIS) model on complex networks, small-world and scale-free, to study epidemic spreading with the effect of time delay…
Properties of weighted complex networks
Xin-Jian Xu, Zhi-Xi Wu, Ying-Hai Wang
We study two kinds of weighted networks, weighted small-world (WSW) and weighted scale-free (WSF). The weight of a link between nodes and in the network is defined…
Spatial prisoner's dilemma game with volunteering in Newman-Watts small-world networks
Zhi-Xi Wu, Xin-Jian Xu, Yong chen +1
A modified spatial prisoner's dilemma game with voluntary participation in Newman-Watts small-world networks is studied. Some reasonable ingredients are introduced to the game evol…
