Abstract

We derive comparison formulas relating the zeta-regularized determinant of an arbitrary self-adjoint extension of the Laplace operator with domain $C^\infty_c(X\setminus \{P\})\subset L_2(X)$ to the zeta-regularized determinant of the Laplace operator on $X$. Here, $X$ is a compact Riemannian manifold of dimension $2$ or $3$; $P\in X$.
