  "abstract": "Let $K=\\mathbb{Q}(\\sqrt[n]{a})$ be an extension of degree $n$ of the field $\\Q$ of rational numbers, where the integer $a$ is such that for each prime $p$ dividing $n$ either $p\\nmid a$ or the highest power of $p$ dividing $a$ is coprime to $p$; this condition is clearly satisfied when $a, n$ are coprime or $a$ is squarefree. The paper contains an explicit formula for the discriminant of $K$ involving only the prime powers dividing $a,n$.",
