Decomposing data sets into skewness modes
Rubén A. Pasmanter, Frank M. Selten
We derive the nonlinear equations satisfied by the coefficients of linear combinations that maximize their skewness when their variance is constrained to take a specific value. In…
Mixing and coherent structures in two-dimensional viscous flows
H. W. Capel, R. A. Pasmanter
We introduce a dynamical description based on a probability density of the vorticity in two-dimensional viscous flows such that the average vorticity evolves accor…
Strong Universality in Forced and Decaying Turbulence
Victor S. L'vov, Ruben Pasmanter, Anna Pomyalov +1
The weak version of universality in turbulence refers to the independence of the scaling exponents of the th order strcuture functions from the statistics of the forcing. The st…
Markov-chain approach to a process with long-time memory
Guglielmo Lacorata, Ruben A. Pasmanter, Angelo Vulpiani
We show that long-term memory effects, present in the chaotic dispersion process generated by a meandering jet model, can be nonetheless taken into account by a first order Markov…
Evolution of the vorticity-area density during the formation of coherent structures in two-dimensional flows
H. W. Capel, R. A. Pasmanter
It is shown: 1) that in two-dimensional, incompressible, viscous flows the vorticity-area distribution evolves according to an advection-diffusion equation with a negative, time de…
Metric structures of inviscid flows
Rubén A. Pasmanter
An intrinsic metric tensor, a flat connexion and the corresponding distance-like function are constructed in the configuration space formed by velocity field {\bf and} the thermody…
