Global Balance and Systemic Risk in Financial Correlation Networks
Paolo Bartesaghi, Fernando Diaz-Diaz, Rosanna Grassi +1
The global balance index is used in the network literature to quantify how balanced a signed network is. In this paper we show that the global balance index of financial correlatio…
Signed graphs in data sciences via communicability geometry
Fernando Diaz-Diaz, Ernesto Estrada
Signed graphs are an emergent way of representing data in a variety of contexts where antagonistic interactions exist. These include data from biological, ecological, and social sy…
Mathematical Modeling of Local Balance in Signed Networks and Its Applications to Global International Analysis
Fernando Diaz-Diaz, Paolo Bartesaghi, Ernesto Estrada
Alliances and conflicts in social, political and economic relations can be represented by positive and negative edges in signed networks. A cycle is said to be positive if the prod…
Time and space generalized diffusion equation on graphs/networks
Fernando Diaz-Diaz, Ernesto Estrada
Normal and anomalous diffusion are ubiquitous in many complex systems [1] . Here, we define a time and space generalized diffusion equation (GDE), which uses fractional-time deriva…
