Consecutive pure fields of the form $\mathbb{Q}\left(\sqrt[l]{a}\right)$ with large class numbers

Abstract

Let $l$ be a rational prime greater than or equal to $3$ and $k$ be a given positive integer. Under a conjecture due to Langlands and an assumption on upper bound for the regulator of fields of the form $\mathbb{Q}\left(\sqrt[l]{a}\right)$, we prove that there are atleast $x^{1/l-o(1)}$ integers $1\le d\le x$ such that the consecutive pure fields of the form $\mathbb{Q}\left(\sqrt[l]{d+1}\right),\dots ,\mathbb{Q}\left(\sqrt[l]{d+k}\right)$ have arbitrary large class numbers.
