|Title:||The deterministic random walk|
|Seminar:||Center for Dynamics and Geometry Seminar|
|Speaker:||Omri Sarig, The Weizmann Institute for Science|
|The simple random walk on Z can be simulated by picking randomly uniformly in the unit interval, iterating T(x)=2x mod 1, and moving the "walker" one step to the right every time the orbit lands at [0,1/2) and one step to the left every time the orbit lands at [1/2,1).
What happens if we replace the chaotic T(x)=2x mod 1 by the zero entropy R(x)=x+\alpha mod 1 for \alpha irrational? The resulting process, called the "deterministic random walk", is again a recurrent zero drift walk -- but one that visits zero much more often.
This is a joint work with Avila, Dolgopyat, and Duriev|
