改进的Bochner不等式在Finsler流形上的一些重要应用

Some important applications of improved Bochner inequality on Finsler manifolds

Xinyue Cheng

摘要:

利用改进的Bochner不等式及其积分形式,在加权里奇曲率$\mathrm{Ric}_{\infty}\geq K$为常数$K >0$的条件下,建立了一些重要的不等式.首先,我们得到了一个尖锐的Poincaré-Lichnerowicz不等式。进一步给出了对数Sobolev不等式的一个新证明。最后,我们得到了测地线球体积的一个估计。

英文摘要:

We establish some important inequalities under the condition that the weighted Ricci curvature $\mathrm{Ric}_{\infty}\geq K$ for some constant $K >0$ by using improved Bochner inequality and its integrated form. Firstly, we obtain a sharp Poincaré-Lichnerowicz inequality. Further, we give a new proof for logarithmic Sobolev inequality. Finally, we obtain an estimate of the volume of geodesic balls.
