具有持久边的时态网络上的随机游动

Random walk on temporal networks with lasting edges

Julien Petit, Martin Gueuning, Timoteo Carletti, Ben Lauwens, Renaud Lambiotte

摘要:

我们考虑在有限时间间隔内边出现和消失的动态网络上的随机游动。该过程是基于三个独立的随机过程确定步行者的等待时间,启动时间和停机时间的边缘激活。我们首先提出了一个全面的分析和数值处理有向无环图。一旦网络中允许循环,非马尔可夫轨迹可能会出现,即使步行者和网络边缘的演化由无记忆泊松过程控制。然后,我们引入了一个一般的分析框架来描述这种非马尔可夫行走,并验证我们的研究结果与数值模拟。

英文摘要:

We consider random walks on dynamical networks where edges appear and disappear during finite time intervals. The process is grounded on three independent stochastic processes determining the walker's waiting-time, the up-time and down-time of edges activation. We first propose a comprehensive analytical and numerical treatment on directed acyclic graphs. Once cycles are allowed in the network, non-Markovian trajectories may emerge, remarkably even if the walker and the evolution of the network edges are governed by memoryless Poisson processes. We then introduce a general analytical framework to characterize such non-Markovian walks and validate our findings with numerical simulations.
