临界Mandelbrot级联的局域涨落

Local fluctuations of critical Mandelbrot cascades

Dariusz Buraczewski, Piotr Dyszewski, Konrad Kolesko

摘要:

我们调查所谓的广义Mandelbrot级联在冻结(临界)温度。我们知道,经过适当的重新标度,一个乘性级联序列弱收敛到某个连续随机测度。我们的主要问题是极限测度$μ$如何波动。对于任何给定的点$x$,用$B_n(x)$表示以$x$为中心的半径为$2^{-n}$的球,我们给出了$μ(B_n(x))$的最优上下估计为$n \to \infty$。

英文摘要:

We investigate so-called generalized Mandelbrot cascades at the freezing (critical) temperature. It is known that, after a proper rescaling, a~sequence of multiplicative cascades converges weakly to some continuous random measure. Our main question is how the limiting measure $μ$ fluctuates. For any given point $x$, denoting by $B_n(x)$ the ball of radius $2^{-n}$ centered around $x$, we present optimal lower and upper estimates of $μ(B_n(x))$ as $n \to \infty$.
