Application of Stochastic Flows to the Sticky Brownian Motion Equation

Hatem Hajri, Caglar Mine, Marc Arnaudon

We show how the theory of stochastic flows allows to recover in an elementary way a well known result of Warren on the sticky Brownian motion equation.

On a coupling of solutions to the interface SDE on a star graph

Hatem Hajri, Marc Arnaudon

Inspired by Tsirelson proof of the non Brownian character of WalshBrownian motion ltration on three or more rays, we prove some results on aparticular coupling of solutions to the…

On flows associated to Tanaka's SDE and related works

Hatem Hajri

We review the construction of flows associated to Tanaka's SDE from [9] and give an easy proof of the classification of these flows by means of probability measures on [0, 1]. Our…

Stochastic flows and an interface SDE on metric graphs

Hatem Hajri, Olivier Raimond

This paper consists in the study of a stochastic differential equation on a metric graph, called an interface SDE . To each edge of the graph is associated an indepe…

Stochastic flows on metric graphs

Hatem Hajri, Olivier Raimond

We study a simple stochastic differential equation driven by one Brownian motion on a general oriented metric graph whose solutions are stochastic flows of kernels. Under some cond…

On the Csáki-Vincze transformation

Hatem Hajri

Cs aki and Vincze have de fined in 1961 a discrete transformation T which applies to simple random walks and is measure preserving. In this paper, we are interested in ergodic and…

Tanaka's equation on the circle and stochastic flows

Hatem Hajri, Olivier Raimond

We define a Tanaka's equation on an oriented graph with two edges and two vertices. This graph will be embedded in the unit circle. Extending this equation to flows of kernels, we…

Discrete approximation to solution flows of Tanaka SDE related to Walsh Brownian motion

Hatem Hajri

In a previous work, we have defined a Tanaka SDE related to Walsh Brownian motion which depends on kernels. It was shown that there are only one Wiener solution and only one flow o…

Stochastic flows related to Walsh Brownian motion

Hatem Hajri

We define an equation on a simple graph which is an extension of Tanaka equation and the skew Brownian motion equation. We then apply the theory of transition kernels developped by…
