Here, we focus on the analysis of the bipartivity of graphs. We first introduce a mathematical approach to quantify bipartivity and show its implementation in general and random graphs. Then, we tackle the analysis of the transportation networks of European airlines from the point of view of their bipartivity and observe significant differences between traditional and low cost carriers. Bipartivity shows also that alliances and major mergers of traditional airlines provide a way to reduce bipartivity which, in its turn, is closely related to an increase of the transportation efficiency. info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP info:eu-repo/grantAgreement/EC/FP7/317532/EU/Foundational Research on MULTIlevel comPLEX networks and systems/MULTIPLEX info:eu-repo/grantAgreement/EC/FP7/317614/EU/Mathematical framework for multiplex networks/PLEXMATH info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 info:eu-repo/grantAgreement/ES/MINECO/FIS2012-38266 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.514 2016 MATHEMATICS, APPLIED 56 / 255 = 0.22 2016 Q1 T1 PHYSICS, MULTIDISCIPLINARY 33 / 79 = 0.418 2016 Q2 T2 PHYSICS, MATHEMATICAL 24 / 55 = 0.436 2016 Q2 T2 0.846 2016 Condensed Matter Physics 2016 Q1 Statistical and Nonlinear Physics 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Gómez Gardeñes, Jesús Universidad de Zaragoza (orcid)0000-0001-5204-1937 2003 395 Universidad de Zaragoza Dpto.
