摘要:

本文利用加权Laplacian度量空间$Δ_f$的第一谱$λ_1(Δ_f)$,即$0<a\leq\dfrac{m}{m-1}, b\geq0$的$\mathrm{Ric}_{m,n}\geq -aλ_1(Δ_f)-b$,研究了完备光滑度量空间$(M^n,g,\mathrm{e}^{-f}\mathrm{d}v)$上具有各种负$m$ -Bakry-Émery- Ricci曲率下界的消失和分裂结果.特别是,我们认为三个主要的情况下,不同的$a$和PDMATHAMT与或不与$λ_1(Δ_f)$的条件。这些结果是Dung和Vieira的推广,也是Li-Wang,Dung-Sung和Vieira的加权推广.

英文摘要:

In this paper, we study vanishing and splitting results on a complete smooth metric measure space $(M^n,g,\mathrm{e}^{-f}\mathrm{d}v)$ with various negative $m$-Bakry-Émery-Ricci curvature lower bounds in terms of the first spectrum $λ_1(Δ_f)$ of the weighted Laplacian $Δ_f$, i.e. $\mathrm{Ric}_{m,n}\geq -aλ_1(Δ_f)-b$ for $0<a\leq\dfrac{m}{m-1}, b\geq0$. In particular, we consider three main cases for different $a$ and $b$ with or without conditions on $λ_1(Δ_f)$. These results are extensions of Dung and Vieira, and weighted generalizations of Li-Wang, Dung-Sung and Vieira.
