关于凸区域的谱隙

On the Spectral Gap for Convex Domains

Burgess Davis, Majid Hosseini

摘要:

我们证明了以下关于两个坐标轴对称的有界凸平面域。考虑一个中心矩形,其边平行于严格包含域的轴。如果域不是某种矩形,则域的谱隙大于矩形的谱隙。我们还提供了明确的下界之间的差距。

英文摘要:

We prove the following for a bounded convex planar domain that is symmetric with respect to both coordinate axes. Consider a centered rectangle with sides parallel to the axes that strictly contains the domain. If the domain is not a certain kind of rectangle, the spectral gap of the domain is larger than the spectral gap of the rectangle. We also provide explicit lower bounds for the differnce between the gaps.
