Abstract:
In this paper we discuss dimensional and cutoff regularizations, using the heat kernel method as an example. The regularization modifications by adding to a Green function a special type operator are considered. In particular, we show that the dimensional regularization can lead to non-logarithmic divergences.
Key words and phrases:
cutoff regularization, dimensional regularization, Green function, heat kernel, non-logarithmic divergence, mixed type regularization.
