This nic e example of a random walk on a dynamical random environment presents its own challenges due to the slow mixing properties of the underlying medium. We will discuss a law of large numbers that has been proved recently for this random walk. Interestingly\, we can only prove this law of large numb ers for all but two exceptional densities of the exclusion process. The ma in technique that we have employed is a multi-scale renormalization that h as been derived from works in percolation theory. X-ALT-DESC:\n
In this talk we will study t he asymptotic behavior of a random walk that evolves on top of a simple sy mmetric exclusion process.
