# On the L p -distortion of finite quotients of amenable groups

On the L p -distortion of finite quotients of amenable groups We study the L p -distortion of finite quotients of amenable groups. In particular, for every $${2\leq p < \infty}$$ , we prove that the ℓ p -distortions of the groups $${C_2\wr C_n}$$ and $${C_{2^n}\rtimes C_n}$$ are in $${\Theta((\log n)^{1/p}),}$$ and that the ℓ p -distortion of $${C_n^2 \rtimes_A \mathbf{Z}}$$ , where A is the matrix $${{\left({\small\begin{array}{cc}2 & 1 \\ 1 & 1 \end{array}} \right)}}$$ is in $${\Theta((\log \log n)^{1/p}).}$$ http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Positivity Springer Journals
