The world of network science is fascinating and filled with complex phenomena that we aspire to understand. One of them is the dynamics of spreading processes over complex networked structures. Building the knowledge-base in the field where we can face more than one spreading process propagating over a network that has more than one layer is a challenging task, as the complexity comes both from the environment in which the spread happens and from characteristics and interplay of spreads' propagation. As this cross-disciplinary field bringing together computer science, network science, biology and physics has rapidly grown over the last decade, there is a need to comprehensively review the current state-of-the-art and offer to the research community a roadmap that helps to organise the future research in this area. Thus, this survey is a first attempt to present the current landscape of the multi-processes spread over multilayer networks and to suggest the potential ways forward.

多层网络中的交互传播过程

网络科学的世界令人着迷，充满了我们渴望了解的复杂现象。其中之一是在复杂的网络结构上传播过程的动态。在我们可以面对多个传播过程的领域中建立知识库，在具有不止一层的网络上传播是一项具有挑战性的任务，因为复杂性既来自传播发生的环境，也来自特征和相互作用点差的传播。由于这个将计算机科学、网络科学、生物学和物理学结合在一起的跨学科领域在过去十年中迅速发展，因此需要全面审查当前的最新技术并向研究界提供一个路线图有助于组织该领域的未来研究。因此，
