title: Condensation phenomena of the generalized conserved-mass aggregation model on complex networks.
abstract: We investigate the condensation phenomena of the generalized symmetric conserved-mass aggregation (GSCA) model on scale-free networks (SFNs) with degree distribution P(k)~k{-γ}. In the GSCA model the whole mass of a node with mass m isotropically diffuses to one of directly linked nodes with rate D(m)=m{-α}. With rate ω, a mass δm=m{-λ} is fragmented from the mass m and also isotropically diffuses. From a mean-field analysis we map out the full α-λ phase diagram for a given γ(≥ 2). We also numerically confirm the mean-field phase diagram.
