Random walks and diameter of finite scale-free networks
Sungmin Lee, Soon-Hyung Yook, Yup Kim
Dynamical scalings for the end-to-end distance and the number of distinct visited nodes of random walks (RWs) on finite scale-free networks (SFNs) are studied numeri…

Condensation phase transitions of symmetric conserved-mass aggregation model on complex networks
Sungchul Kwon, Sungmin Lee, Yup Kim
We investigate condensation phase transitions of symmetric conserved-mass aggregation (SCA) model on random networks (RNs) and scale-free networks (SFNs) with degree distribution $…

Coevolutionary dynamics on scale-free networks
Sungmin Lee, Yup Kim
We investigate Bak-Sneppen coevolution models on scale-free networks with various degree exponents including random networks. For , the critical fitness value approa…
