Speed Function for Biased Random Walks with Traps (2209.00241v1)
Published 1 Sep 2022 in math.PR, math-ph, and math.MP
Abstract: We consider a biased nearest-neighbor random walk on $\Z$ which at each step is trapped for some random time with random, site-dependent mean. We derive a simple formula for the speed function in terms of the model parameters.
