Unramified Quaternion Extensions of Quadratic Number Fields, by Franz Lemmermeyer
This paper has appeared in J. Theor. Nombres Bordeaux 9 (1997), no.1,
51-68, and so the dvi version has been removed.
In this article we show how to construct unramified
quaternion extensions of quadratic number fields by
completely elementary methods.
