论文摘要
我们通过将复发网络与多重网络方法相结合，以研究多元时间序列，引入了一种新型的多重复发网络（MRN）方法。这种方法的潜在用途在耦合的地图晶格上证明了这一方法，也是古植物学研究中的典型例子。在这两个示例中，多重复发网络中的拓扑变化允许检测其动力学的状态变化。该方法通过考虑整体植被以及使用不同区域植被元素的动力学中的固有相似性来超越对花粉记录的经典解释。我们发现，当一个环境因素充当主要驱动力时，不同植被类型的行为更加相似。
We have introduced a novel multiplex recurrence network (MRN) approach by combining recurrence networks with the multiplex network approach in order to investigate multivariate time series. The potential use of this approach is demonstrated on coupled map lattices and a typical example from palaeobotany research. In both examples, topological changes in the multiplex recurrence networks allow for the detection of regime changes in their dynamics. The method goes beyond classical interpretation of pollen records by considering the vegetation as a whole and using the intrinsic similarity in the dynamics of the different regional vegetation elements. We find that the different vegetation types behave more similar when one environmental factor acts as the dominant driving force.
