monochromatic solution to $xy=z$

$begingroup$


Is it true that for any $k geq 2$, there is an integer $n=n(k)$ such that for any $k$-coloring of ${1,...,n},$ the equation $xy=z$ has a monochromatic solution?

          Some hints :



          This is a simple modification of Schur's theorem via an exponential.



          This document from EPFL on page 35 contains a proof of Schur's theorem which you can adapt to your problem.
