已开发的形式主义，给出微分算子的行列式的一般表达式扩展到物理上有趣的情况下，这些运营商有一个零模式，已被提取。在这里采用的方法中，这种模式被删除一个新的正则化过程，它允许非常简单的表达式，这些决定因素推导。
The formalism which has been developed to give general expressions for the determinants of differential operators is extended to the physically interesting situation where these operators have a zero mode which has been extracted. In the approach adopted here, this mode is removed by a novel regularization procedure, which allows remarkably simple expressions for these determinants to be derived.
