Imaginary Quadratic Fields k with Cyclic Cl_2(k^1), by Elliot Benjamin, Franz Lemmermeyer, Chip Snyder
This paper has appeared in J. Number Theory 67 (1997), no. 2, 229-245,
and so the dvi version has been removed. Let $k$ be an imaginary quadratic number field, and let
$k^1$ denote its Hilbert $2$-class field. In this paper,
we determine the fields $k$ such that the $2$-class group
of $k^1$ is cyclic. In particular, such fields have
terminating $2$-class field tower.
