Abstract

The multilayered structure of the European airport network (EAN), composed of connections and flights between European cities, is analyzed through the k-core decomposition of the connections network. This decomposition allows to identify the core, bridge and periphery layers of the EAN. The core layer includes the best-connected cities, which include important business air traffic destinations. The periphery layer includes cities with lesser connections, which serve low populated areas where air travel is an economic alternative. The remaining cities form the bridge of the EAN, including important leisure travel origins and destinations. The multilayered structure of the EAN affects network robustness, as the EAN is more robust to isolation of nodes of the core, than to the isolation of a combination of core and bridge nodes.

Abstract

Interlocking directorates build relationships between corporations, and define the national economic organization. We analyze the corporate network of the IBEX 35 companies, plus two savings banks, and compare it with the same network in 2005. The most central positions in the network are occupied by large Spanish corporations, privatized in the 90s. On the other hand, in 2008 banks lose centrality, while savings bank’s centrality rises.
