A particularly advantageous way to study these systems is through the analysis of the networks that encode the interactions among the system constituents. During the past two decades, network science has provided many insights in natural, social, biological, and technological systems. However, real systems are often interconnected, with many interdependencies that are not properly captured by single-layer networks. To account for this source of complexity, a more general framework, in which different networks evolve or interact with each other, is needed. These are known as multilayer networks. Here, we provide an overview of the basic methodology used to describe multilayer systems as well as of some representative dynamical processes that take place on top of them. We round off the review with a summary of several applications in diverse fields of science. 000084319 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E36-17R$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2017-87519-P 000084319 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000084319 590__ $$a14.833$$b2019 000084319 592__ $$a8.574$$b2019 000084319 591__ $$aPHYSICS, CONDENSED MATTER$$b6 / 69 = 0.087$$c2019$$dQ1$$eT1 000084319 593__ $$aMaterials Science (miscellaneous)$$c2019$$dQ1 000084319 593__ $$aCondensed Matter Physics$$c2019$$dQ1 000084319 655_4 $$ainfo:eu-repo/semantics/review$$vinfo:eu-repo/semantics/acceptedVersion 000084319 700__ $$0(orcid)0000-0002-0895-1893$$aMoreno, Y.$$uUniversidad de Zaragoza 000084319 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
