# The K-theoretic Farrell-Jones conjecture for cat(0) groups

Is the fibered K-theoretic farrell-jones conjecture true for cat(0)-groups?

-

Yes. More precisely, both the L-theory and K-theory Farrell-Jones conjectures with coefficients in any additive category have recently been proved for CAT(0) groups:

In Arthur Bartels, Holger Reich, “Coefficients for the Farrell-Jones Conjecture”, Advances in Mathematics 209:1 (2007), 337–362, it is proved that “with coefficients is stronger than fibered,” see Corollary 4.3 and Remark 4.4 on page 346.

[Edited to clarify the relation between the “with coefficients” and “fibered” versions of the Farrell-Jones conjectures.]

But also they proved the fibered version? –  Luis Jorge Feb 22 '12 at 18:51
Yes, see the paragraph I added above. –  Marco Varisco Feb 22 '12 at 19:05
Thank you very much for your answer. –  Luis Jorge Feb 22 '12 at 20:46

You are welcome, Luis! And thanks a lot, Dan! Finally, right? –  Marco Varisco Feb 23 '12 at 11:26
