广义锥上泛函行列式的小质量展开

Small Mass Expansion of Functional Determinants on the Generalized Cone

Guglielmo Fucci, Klaus Kirsten

摘要:

在本文中,我们计算的小质量展开的功能行列式的标量拉普拉斯定义在有界的,广义锥。在zeta函数正则化的框架下,我们得到了一个在任意维Dirichlet和Robin边界条件下都有效的泛函行列式的表达式,它是由基流形的谱zeta函数表示的.此外,作为一个特殊的情况下,我们指定的基础是一个$d$-维球和$d=2,3,4,5$目前明确的结果。

英文摘要:

In this paper we compute the small mass expansion for the functional determinant of a scalar Laplacian defined on the bounded, generalized cone. In the framework of zeta function regularization, we obtain an expression for the functional determinant valid in any dimension for both Dirichlet and Robin boundary conditions in terms of the spectral zeta function of the base manifold. Moreover, as a particular case, we specify the base to be a $d$-dimensional sphere and present explicit results for $d=2,3,4,5$.
