热核的共形摄动及其应用

Conformal Perturbation of Heat Kernels with applications

Shiliang Zhao

摘要:

设$(M, g)$是$n\ge 2$的光滑n维黎曼流形.考虑共形扰动$\tilde{g}=h g$,其中$h$是$M$上的光滑有界正函数。用$\tilde{p}_t(x,y)$表示流形$(M, \tilde{g})$的热核。本文给出了$\tilde{p}_t(x,y)$的上界和梯度估计。

英文摘要:

Let $(M, g)$ be a smooth n-dimensional Riemannian manifold for $n\ge 2$. Consider the conformal perturbation $\tilde{g}=h g$ where $h$ is a smooth bounded positive function on $M$. Denote by $\tilde{p}_t(x,y)$ the heat kernel of manifolds $(M, \tilde{g})$. In this paper, we derive the upper bounds and gradient estimates of $\tilde{p}_t(x,y)$.
