We develop elements of a theory of cooperation and coordination in networks. Rather than considering a communication network as a means of distributing information, or of reconstructing random processes at remote nodes, we ask what dependence can be established among the nodes given the communication constraints. Specifically, in a network with communication rates between the nodes, we ask what...

On October 18, 1996, hundreds of people, including many mathematicians, gathered at Kerepesi Cemetery in Budapest to pay their last respects to Paul Erdős. If there was one theme suggested by the farewell orations, it was that the world of mathematics had lost a legend, one of its great representatives. On October 21, 1996, in accordance with his last wishes, Paul Erdős’ ashes were buried in hi...

Location awareness is a key enabler for a multitude of indoor applications, such as logistics, intelligent warehouses, or flexible production. The robust provision of accurate position information requires a careful fusion of location-dependent parameters acquired by various sensors, including range measurements from radio signals. The latter are the basis for successful outdoor localization sy...

Old elites can block changes, but not all do. Why is it that stronger elites may allow more changes than weaker elites? Why do economies with larger stocks of natural resources not grow faster than economies poorer in natural resources? We argue that old elites hold some power to extract rents from the economy. Whereas old sectors (i.e. agriculture or extraction of natural resources) are not af...
