报告题目：Bilinear and Fractional Leibniz Rules Beyond Euclidean Spaces: Weighted Besov and Triebel-Lizorkin Estimates

时 间：2026年11月12日(星期四)上午10:00

地 点：理工楼601

报告摘要：This talk presents new fractional Leibniz rules in weighted settings for nonnegative self-adjoint operators on spaces of homogeneous type. The unified approach, which avoids Fourier transform techniques, establishes bilinear estimates for spectral multipliers on weighted Hardy, Besov, and Triebel-Lizorkin spaces. The framework extends beyond Euclidean contexts, encompassing examples such as nilpotent Lie groups, Grushin operators, and Hermite expansions.
