upper bound on sum of product of binomial coefficients
@Ilya Bogdanoiv. You are right. Giving a too simple answer can be a way to get more precisions on the nature of the bound wished (is it wanted for $\ell/m$ close to $0$, close to $1/2$, close to $1$ ?). Anyway, I completed my answer to give a less trivial bound when $\ell \ge m/2$.

Lower bound for nonconventional ergodic averages in finite fields
I added a missing $f$, and the word « positive » before constant.

@Mikhail Tikhomirow Yes you are right. I had misread, sorry. I will suppress this comment.
