免疫接种引起的远距离传染病传播

Long-range epidemic spreading with immunization

Florian Linder, Johannes Tran-Gia, Silvio R. Dahmen, Haye Hinrichsen

摘要:

我们研究了具有长程相互作用和免疫的流行病过程中生存和灭绝之间的相变。该模型可以看作是著名的一般流行病过程(GEP),其中最近邻相互作用被分布为P(r)~ r^(-d-sigma)的距离r上的Levy飞行所代替。通过大量的数值模拟,我们证实了Janssen等人[Eur. B7,137(1999)]。

英文摘要:

We study the phase transition between survival and extinction in an epidemic process with long-range interactions and immunization. This model can be viewed as the well-known general epidemic process (GEP) in which nearest-neighbor interactions are replaced by Levy flights over distances r which are distributed as P(r) ~ r^(-d-sigma). By extensive numerical simulations we confirm previous field-theoretical results obtained by Janssen et al. [Eur. Phys. J. B7, 137 (1999)].
