What is $e^{- \zeta_{\Delta} '(0)}$ for a $\Delta$ the Laplacian of a manifold?
For a connected, finite graph $G$, let $\lambda_1, \ldots, \lambda_n$ denote the nonzero eigenvalues of the graph Laplacian. We define $\zeta_G = \Sigma_{i = 1}^n \lambda_i^s$.
Then Kirkoffs Matrix-T …

Discrete approximation of Minkshisundaram-Pleijel zeta function?
I'm looking for some references on the following situation:
$S$ is a Riemannian surface, and $G_n$ is a sequence of metric subgraphs embedded on $S$. Let $\zeta_n$ be the zeta function of the Laplac …

Discrete approximation of Minkshisundaram-Pleijel zeta function?
I learned of a few results that give useful answers to (the spirit of) this question:
Zeta functions, heat kernels and spectral asymptotics on
degenerating families of discrete tori ( G. Chinta, J. J …

Does the zeta regularized Laplacian determinant measure the volume of some parameter space? ...
Let $(M,g)$ be a Riemannian manifold, with Laplacian $\Delta$. If $\lambda_i$ are the nonzero eigenvalues of $\Delta$, we can define the zeta function $\zeta(s) = \Sigma \lambda_i^{-s}$. By analytic c …
