Jan 24, 2019 at 16:58 comment added ARG @PiotrHajlasz I did not read anything stupid... The reference for the english survey of Pittet and Saloff-Coste is "A survey on the relationships between volume growth, isoperimetry, and the behavior of simple random walk on Cayley graphs, with examples". It is freely available if you google it. The result is section 4 of this survey.

Jan 24, 2019 at 16:51 comment added Piotr Hajlasz @ARG Thank you for details. I was not aware of this result. I will read your proof and erase my stupid comments about counterexamples.
Jan 24, 2019 at 16:08 comment added ARG @PiotrHajlasz Many thanks for the details in the $\ell^p$-$\ell^q$-case. As I mentioned, the $\ell^1$-inequality is known to hold in all Cayley graphs (not just those of polynomial growth). I added the proof in case you are curious about it.
