Ergodicity of Stochastically Forced Large Scale Geophysical Flows

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 6, Page 313-320, 2001., 2001
We investigate the ergodicity of 2D large scale quasigeostrophic flows under random wind forcing. We show that the quasigeostrophic flows are ergodic under suitable conditions on the random forcing and on the fluid domain, and under no restrictions on ...

Low complexity subshifts have discrete spectrum

open access: yesForum of Mathematics, Sigma, 2023
We prove results about subshifts with linear (word) complexity, meaning that $\limsup \frac {p(n)}{n} < \infty $ , where for every n, $p(n)$ is the number of n-letter words appearing in sequences in the subshift.

Theoretical analysis and computational modeling of nonlinear fractional-order victim-two predators model

open access: yesResults in Physics, 2022
The victim-predator model has been investigated in several papers in the literature since it is considered one of the very important models. The relation between predator and victim is an important aspect of ecology. The principal object of this research

Chaotic tracial dynamics

open access: yesForum of Mathematics, Sigma, 2023
The action on the trace space induced by a generic automorphism of a suitable finite classifiable ${\mathrm {C}^*}$ -algebra is shown to be chaotic and weakly mixing.

Thermalization in Kitaev’s quantum double models via tensor network techniques

open access: yesForum of Mathematics, Sigma, 2023
We show that every ergodic Davies generator associated to any 2D Kitaev’s quantum double model has a nonvanishing spectral gap in the thermodynamic limit.

Uncomputably noisy ergodic limits [PDF]

open access: yes, 2011
V'yugin has shown that there are a computable shift-invariant measure on Cantor space and a simple function f such that there is no computable bound on the rate of convergence of the ergodic averages A_n f. Here it is shown that in fact one can construct

On modelling of epidemic childhood diseases with the Caputo-Fabrizio derivative by using the Laplace Adomian decomposition method

open access: yesAlexandria Engineering Journal, 2020
We present a fractional-order epidemic model for childhood diseases with the new fractional derivative approach proposed by Caputo and Fabrizio. By applying the Laplace Adomian decomposition method (LADM), we solve the problem and the solutions are ...
