黎曼帽上Laplace算子的Zeta行列式

Zeta Determinant for Laplace Operators on Riemann Caps

Antonino Flachi, Guglielmo Fucci

摘要:

本文的目标是计算黎曼帽(或球形悬浮体)上的大质量拉普拉斯算子的zeta函数行列式。这些流形被定义为紧的和无边界的$D-$维流形变形的奇异黎曼结构。变形球,以前在文献中考虑,属于这一类。在介绍了拉普拉斯算子的几何和讨论了拉普拉斯算子的谱之后,我们说明了一种计算其zeta正则化行列式的方法。变形球的特殊情况恢复作为我们的一般公式的限制。

英文摘要:

The goal of this paper is to compute the zeta function determinant for the massive Laplacian on Riemann caps (or spherical suspensions). These manifolds are defined as compact and boundaryless $D-$dimensional manifolds deformed by a singular Riemannian structure. The deformed spheres, considered previously in the literature, belong to this class. After presenting the geometry and discussing the spectrum of the Laplacian, we illustrate a method to compute its zeta regularized determinant. The special case of the deformed sphere is recovered as a limit of our general formulas.
