Impact of Nonlinearity on Statistics in Physical Systems
Jérôme KASPARIAN, https://www.unige.ch/gap/nonlinear/people/jerome-kasparian/GAP, Nonlinearity and Climate, University of Geneva

ABSTRACT:
Many physical processes are nonlinear, from lasers to the climate to oceanic wave propagation. But usual statistical distribution, like the Gaussian, rely on the assumption of linearity. We will discuss examples where nonlinearity deforms the statistical distributions towards more skewness, drastically increasing the relative weight of extreme events.
Nonlinearity also brings feedbacks that can lead to multiple alternative stable states, or attractors, with, again specific implications on statistical distributions of the system characteristics, especially in transition regimes.
