DESCRIPTION:The study of networks plays a crucial role in investigating th
 e structure\, dynamics\, and function of a wide variety of complex systems
  in myriad disciplines. Despite the success of traditional network analysi
 s\, standard networks provide a limited representation of complex systems\
 , which often include different types of relationships (i.e.\, &ldquo\;mul
 tiplexity&rdquo\;) among their constituent components and/or multiple inte
 racting subsystems. Such structural complexity has a significant effect on
  both dynamics and function. Throwing away or aggregating available struct
 ural information can generate misleading results and be a major obstacle t
 owards attempts to understand complex systems. The recent &ldquo\;multilay
 er&rdquo\; approach for modeling networked systems explicitly allows the i
 ncorporation of multiplexity and other features of realistic systems. On o
 ne hand\, it allows one to couple different structural relationships by&nb
 sp\;encoding them in a convenient mathematical object. On the other hand\,
  it also allows one to couple different dynamical processes on top of such
  interconnected structures. The resulting framework plays a crucial role i
 n helping achieve a thorough\, accurate understanding of complex systems. 
 The study of multilayer networks has also revealed new physical phenomena 
 that remain hidden when using ordinary graphs\, the traditional network re
 presentation. Here we survey progress towards attaining a deeper understan
 ding of spreading processes on multilayer networks\, and we highlight some
  of the physical phenomena related to spreading processes that emerge from
  multilayer structure.
