A family of crystallographic groups with 2-torsion in K0 of the rational group algebra
Published online by Cambridge University Press: 20 January 2009
Extract
We calculate K0 of the rational group algebra of a certain crystallographic group, showing that it contains an element of order 2. We show that this element is the Euler class, and use our calculation to produce a whole family of groups with Euler class of order 2.
