| Feb 6, 2010 at 10:49 | comment | added | darij grinberg | Okay, I now found the first page of the reference: reference-global.com/doi/abs/10.1515/crll.1983.341.87 and indeed it claims that the Burnside ring is just pre-$\lambda$ rather than $\lambda$. And a reference to Siebeneicher claiming that it is $\lambda$ if $G$ is cyclic (which should be Witt vector theory again). My question is settled. | |
| Feb 6, 2010 at 9:39 | comment | added | darij grinberg | Thanks a lot. This kills the conjecture at least. I assume that for cyclic $K$, it is not particularly hard (one can wlog assume that $G=K$, and $B\left(G\right)$ for cyclic $G$ should be some kind of stunted Witt rings). | |
