Direct Statistical Simulation Using Generalised Cumulant Expansions
G. V. Nivarti, J. B. Marston, S. M. Tobias
In recent years, the Generalised Quasilinear (GQL) approximation has been developed and its efficacy tested against purely quasilinear (QL) approximations. GQL systematically inter…

Non-equivalence of quasilinear dynamical systems and their statistical closures
G. V. Nivarti, R. R. Kerswell, J. B. Marston +1
It is widely believed that statistical closure theories for dynamical systems provide statistics equivalent to those of the governing dynamical equations from which the former are…
