%0 Journal Article %T Adams operations on the Green ring of a cyclic group of prime-power order %A R. M. Bryant %A Marianne Johnson %J Mathematics %D 2009 %I arXiv %X We consider the Green ring $R_{KC}$ for a cyclic $p$-group $C$ over a field $K$ of prime characteristic $p$ and determine the Adams operations $\psi^n$ in the case where $n$ is not divisible by $p$. This gives information on the decomposition into indecomposables of exterior powers and symmetric powers of $KC$-modules. %U http://arxiv.org/abs/0912.1524v1
