Moments and logarithmic intermittency of the Critical 2D Stochastic Heat Flow
Speaker: Prof. Kyeongsik Nam (Korea Advanced Institute of Science and Technology)
Thời gian: 14h chiều Thứ 5, ngày 22/10/2026
Địa điểm: Phòng 507 nhà A6
Tóm tắtt: The critical 2D stochastic heat flow (SHF) is a universal random measure arising from 2D stochastic heat equation or directed polymers at critical disorder. It is singular with respect to Lebesgue measure and exhibits intermittency. In this talk, I will discuss two complementary aspects of this behavior. First, I will present higher moment estimates of SHF. Then I will describe a microscopic geometry of SHF, which reveals logarithmic fractal dimension.
