*Title: *The lower algebraic K-theory of split three-dimensional
crystallographic groups
 *
Abstract:* In 2006, Alves and Ontaneda gave a formula for the Whitehead
group of a 3-dimensional crystallographic group G in terms of the
Whitehead groups of the virtually infinite cyclic subgroups of G . In this
talk, I will present a general splitting formula for the lower algebraic
K-theory of all 3-dimensional crystallographic groups, which generalizes
the one for the Whitehead group obtained by Alves and Ontaneda. This joint
work with Dan Farley.
