Abstract

In this paper we show there exists an infinite family of number fields $L$ , Galois over $ℚ$ , for which the smallest prime $p$ of $ℚ$ which splits completely in $L$ has size at least ${(log (| D_{L} |))}^{2 + o (1)}$ . This gives a converse to various upper bounds, which shows that they are best possible.
