SFI working group fits missing piece to statistics of complex systems 

In February of 2020, [Constantino] Tsallis, mathematician Nihat Ay, and physicist Ugur Tirnakli convened a small SFI working group to focus on the mathematical counterpart of the third signature of nonextensive statistical mechanics, namely the distribution of energies. They have published their results in a recent paper in the journal Nonlinear Dynamics.

In the paper, they demonstrate how non-extensive statistical mechanics mirrors the large deviation theory, related to the long-awaited third signature in these statistics for complex systems. They go on to computationally test their approach on iconic models of complex systems that describe earthquakes, avalanches, and extinction of biological species.
