The Brauer-Siegel ratio for prime cyclotomic fields

Number Theory 2025-02-04 v2

Abstract

The Brauer-Siegel theorem concerns the size of the product of the class number and the regulator of a number field KK. We derive bounds for this product in case KK is a prime cyclotomic field, distinguishing between whether there is a Siegel zero or not. In particular, we make a result of Tatuzawa (1953) more explicit. Our theoretical advancements are complemented by numerical illustrations that are consistent with our findings.
