Littlewood-Richardson rule for $F\wr S_{n}$
We give a new proof for the Littlewood-Richardson rule for the wreath product $F\wr S_{n}$ where $F$ is a finite group. Our proof does not use symmetric functions but more elementary representation theoretic tools. We also derive a branching rule for inducing $F\wr S_{n}$ to $F\wr S_{n+1}$.
