Aw. Janicki et Wa. Woyczynski, HAUSDORFF DIMENSION OF REGULAR POINTS IN STOCHASTIC BURGERS FLOWS WITH LEVY ALPHA-STABLE INITIAL DATA, Journal of statistical physics, 86(1-2), 1997, pp. 277-299
This paper studies statistical properties of shocks for the inviscid B
urgers equation with an alpha-stable Levy motion initial data. In the
absence of analytic results, numerical and computer simulation tools a
re utilized. Qualitative and quantitative information on the scaling p
roperties of Lagrangian regular points of solutions is obtained and, i
n particular, their Hausdorff dimension is estimated to be 1/alpha. Th
is suggests a possible extension of Ya. Sinai's result for Brownian in
itial data.
