E. Aurell et al., BIFRACTALITY OF THE DEVILS STAIRCASE APPEARING IN THE BURGERS-EQUATION WITH BROWNIAN INITIAL VELOCITY, Journal of statistical physics, 88(5-6), 1997, pp. 1151-1164
It is shown that the inverse Lagrangian map for the solution of the Bu
rgers equation (in the inviscid limit) with Brownian initial velocity
presents a bifractality (phase transition) similar to that of the Devi
l's staircase for the standard triadic Canter set. Both heuristic and
rigorous derivations are given. It is explained why artifacts can easi
ly mask this phenomenon in numerical simulations.
