We investigate the long-term behavior of a random walker evolving on top of the simple symmetric exclusion … WebAug 30, 2024 · 2. Start by defining the Symmetric Random Walk: M t = ∑ i = 1 t X i, with X 0 = 0. where X i is equal to 1 or -1 with p = ( 1 − p) = 0.5. Consider t > s, the variance of its increments is: V A R ( M t − M s) = V A R ( ∑ i = s + 1 t X i) by indepence of X i = ∑ i = s + 1 t V A R ( X i) = t − s. Now define the Scaled Symmetric Random ...
