Understanding causation via correlations and linear response theory

by Angelo Vulpiani (Sapienza Università di Roma)

Europe/Rome
Description

In spite of the (correct) common-wisdom statement correlation does not imply causation, a proper employ of time correlations and of fluctuation-response theory allows us to understand causal relations between variables of a multidimensional linear Markov process.  It is shown that fluctuation-response formalism can be used both to find direct causal links between variables of a system and to introduce a degree of causation, cumulative in time, whose physical interpretation is straightforward. Although for generic nonlinear dynamics there is no simple exact relationship between correlations and response functions....
