k-core structure of real multiplex networks Saeed Osat,1, ∗ Filippo Radicchi,2 and Fragkiskos Papadopoulos3 1 Deep Quantum Labs, Skolkovo Institute of Science and Technology, Moscow 143026, Russia 2 Center for Complex Networks and Systems Research, Luddy School of Informatics, Computing, and Engineering, Indiana University, Bloomington, Indiana 47408, USA 3 Department of Electrical Engineering, Computer Engineering and Informatics, Cyprus University of Technology, 33 Saripolou Street, 3036 Limassol, Cyprus (Dated: November 26, 2019) Multiplex networks are convenient mathematical representations for many real-world – biologi- cal, social, and technological – systems of interacting elements, where pairwise interactions among elements have different flavors. Previous studies pointed out that real-world multiplex networks dis- play significant inter-layer correlations – degree-degree correlation, edge overlap, node similarities – able to make them robust against random and targeted failure
