Abstract In this work, we study a stochastic version of the Friedmann acceleration equation. This model has been proposed in cosmology literature as possible explanation uncertainty found experimental quantification Hubble parameter. Its noise tacitly interpreted Stratonovich sense. Herein, prove that interpretation leads to positive probability finite-time blowup solution, is, contrast, if jus...

Abstract The limit from an Euler-type system to the 2D Euler equations with Stratonovich transport noise is investigated. A weak convergence result for vorticity field and a strong velocity are proved. Our results aim provide stochastic reduction of fluid-dynamics models three different time scales.
