On S3-extensions with infinite class field tower
Published 7 Aug 2013 in math.NT | (1308.1572v2)
Abstract: We construct a class of $S_3$-extensions of $\Q$ with infinite 3-class field tower in which only three primes ramify. As an application, we obtain an $S_3$-extension of $\Q$ with infinite 3-class field tower with smallest known (to the author) root discriminant among all fields with infinite 3-class field tower.
