Title: Stiefel-Whitney classes, united K-theory and real embeddings of
number rings
e-mail: mitchell@math.washington.edu

We study the relations among the Stiefel-Whitney classes associated to
the real embeddings of a number ring. Our results depend on a
computation of the real and self-conjugate K-theory of the algebraic
K-theory spectrum of the number ring.
