### A Caveat on the Isomorphism Conjecture in L-theory, by Tom Farrell, Lowell Jones, and Wolfgang Lueck

The Isomorphism Conjecture of Farrell and Jones for L-theory
has only been formulated for the decoration -infinity
and in this formulation been proved for a large class of groups.
The question arises whether the corresponding conjecture is true for
L^e for the decorations e = p,h,s.
We give examples showing that it fails for any of the decorations
e = p,h,s. The groups involved are products
of finite groups by the free abelian group of rank two.
