Logarithmic fluctuations of Stationary Hastings-Levitov
Logarithmic fluctuations of Stationary Hastings-Levitov
We prove that the fluctuation field $\{M_t(x)\}_{x\in\mathbb{R}}$ of stationary Hastings-Levitov$(0)$ exhibits logarithmic spatial correlations. Moreover, by studying the infinitesimal generator of the imaginary part of $M_t(0)$, we show that for some $\beta>0$, $\max_{x\in[0,t]}\text{Im} M_t(x)<\beta\log t$ with high probability, as $t\to\infty$.
