摘要:

在岩-纸-岩(RPS)模型的演化动力学中,自然死亡效应在决定系统命运方面起着重要作用。共存,是一个不稳定的不动点的模型变得非常敏感,对这个参数。为了研究在这样一个系统中的流动性的影响,它有明确的依赖于死亡率,我们进行蒙特卡罗模拟$2$维晶格具有三个循环竞争物种。研究了两点关联函数的时空动力学。空间分布表现出出现的螺旋图案的扩散的存在。它揭示了死亡率和扩散(迁移)的共同作用导致了新的共存和灭绝情景。

英文摘要:

In the evolutionary dynamics of a rock-paper-scissor (RPS) model, the effect of natural death plays a major role in determining the fate of the system. Coexistence, being an unstable fixed point of the model becomes very sensitive towards this parameter. In order to study the effect of mobility in such a system which has explicit dependence on mortality, we perform Monte Carlo simulation on a $2$-dimensional lattice having three cyclically-competing species. The spatio-temporal dynamics has been studied along with the two-site correlation function. Spatial distribution exhibits emergence of spiral patterns in the presence of diffusion. It reveals that the joint effect of death rate and diffusion (migration) leads to new coexistence and extinction scenarios.
