We develop a new multi-scale framework flexible enough to solve a number of problems involving embedding random sequences into random sequences. Grimmett, Liggett and Richthammer [14] asked whether there exists an increasing M -Lipschitz embedding from one i.i.d. Bernoulli sequences into an independent copy with positive probability. We give a positive answer for large enough M . A closely related problem is to show that two independent Poisson processes on R are roughly isometric (or quasi-isometric). Our approach also applies in this case answering a conjecture of Szegedy and of Peled [22] . Our theorem also gives a new proof to Winkler's compatible sequences problem.
In REF , a multi-scale structure was developed which was flexible enough to solve a number of embedding question.
