Ripples and Ripples
T. Aste, U. Valbusa
We study the morphological evolution of surfaces during ion sputtering and we compare their dynamical roughening with aeolian ripple formation in sandy deserts. We show that, altho…
Complex Networks on Hyperbolic Surfaces
T. Aste, T. Di Matteo, S. T. Hyde
We explore a novel method to generate and characterize complex networks by means of their embedding on hyperbolic surfaces. Evolution through local elementary moves allows the expl…
Innovation flow through social networks: Productivity distribution
T. Di Matteo, T. Aste, M. Gallegati
A detailed empirical analysis of the productivity of non financial firms across several countries and years shows that productivity follows a non-Gaussian distribution with power l…
Long term memories of developed and emerging markets: using the scaling analysis to characterize their stage of development

An interest rates cluster analysis
