We consider the evolution of a connected set on the plane carried by a space periodic incompressible stochastic flow. While for almost every realization of the stochastic flow at time t most of the particles are at a distance of order $\sqrt{t}$ away from the origin, there is a measure zero set of points that escape to infinity at the linear rate. We study the set of points visited by the original set by time t and show that such a set, when scaled down by the factor of t, has a limiting…
Long time behaviour of periodic stochastic flows

We consider the evolution of a set carried by a space periodic incompressible stochastic flow in a Euclidean space. We report on three main results obtained in [8, 9, 10] concerning long time

AbstractWe consider the evolution of a connected set in Euclidean space carried by a periodic incompressible stochastic flow. While for almost every realization of the random flow at time t most of
Asymptotic support theorem for planar isotropic Brownian flows
It has been shown by various authors that the diameter of a given nontrivial bounded connected set X grows linearly in time under the action of an isotropic Brownian flow (IBF), which has a
Some Asymptotic Properties of Stochastic Flows
The present work treats several asymptotic properties of stochastic flows on Rd, whose distributions are frequently assumed to be invariant under rotations of the state space. These stochastic flows
Exponential growth rate for derivatives of stochastic flows
• Mathematics

We show that for a large class of stochastic flows the spatial derivative grows at most exponentially fast even if one takes the supremum over a bounded set of initial points. We derive explicit
Asymptotic Growth of Spatial Derivatives of Isotropic Flows

It is known from the multiplicative ergodic theorem that the norm of the derivative of certain stochastic flows at a previously fixed point grows exponentially fast in time as the flows evolves. We
Relative dispersion in 2D stochastic flows
We investigate the relative dispersion for two types of stochastic flows—Brownian flow (Kraichnan model) and a flow with memory (inertial particles). In the first case well-known asymptotics are

The main result is an asymptotic formula for the reachable set, which reveals the structure of the attractor — the set of all limit shapes of the Reachable sets.
Some properties of isotropic Brownian and Ornstein-Uhlenbeck flows
In this thesis we study some macroscopic properties of isotropic Brownian flows (IBF) and isotropic Ornstein-Uhlenbeck flows (IOUF) in Rd with d ≥ 2. IBFs were studied extensively by Baxendale and
A Weak Limit Shape Theorem For Planar Isotropic Brownian Flows
It has been shown by various authors under different assumptions that the diameter of a bounded non-trivial set $\gamma$ under the action of a stochastic flow grows linearly in time. We show that the
