In this expository article, we compare Malle’s conjecture on counting number fields of bounded discriminant with recent conjectures of Ellenberg–Satriano–Zureick-Brown and Darda–Yasuda on counting points of bounded height on classifying stacks. We illustrate the comparisons via the classifying stacks \(B(\mathbb {Z}/n\mathbb {Z})\) and \(B\mu _n\) .

摘要

In this expository article, we compare Malle’s conjecture on counting number fields of bounded discriminant with recent conjectures of Ellenberg–Satriano–Zureick-Brown and Darda–Yasuda on counting points of bounded height on classifying stacks. We illustrate the comparisons via the classifying stacks \(B(\mathbb {Z}/n\mathbb {Z})\) and \(B\mu _n\) .
