Hyun Keun Lee, Yong Woon Kim
We study the formation of public opinion in a poll process where the current score is open to public. The voters are assumed to vote probabilistically for or against their own pref…
Comment on "Nature of the Epidemic Threshold for the Susceptible-Infected-Susceptible Dynamics in Networks" [arXiv:1305.4819]
Hyun Keun Lee, Pyoung-Seop Shim, Jae Dong Noh
Recently, Boguñá {\it et. al.} [Phys. Rev. Lett. {\bf 111}, 068701 (2013), arXiv:1305.4819] claimed that the epidemic threshold of the susceptible-infected-susceptible (SIS) model…
Epidemic Threshold of Susceptible-Infected-Susceptible Model on Complex Networks
Hyun Keun Lee, Pyoung-Seop Shim, Jae Dong Noh
We demonstrate that the susceptible-infected-susceptible (SIS) model on complex networks can have an inactive Griffiths phase characterized by a slow relaxation dynamics. It contra…
Collective Helping and Bystander Effects in Coevolving Helping Networks
Hang-Hyun Jo, Hyun Keun Lee, Hyunggyu Park
We study collective helping behavior and bystander effects in a coevolving helping network model. A node and a link of the network represents an agent who renders or receives help…
