Title: Hindmanâ€™s conjecture over the rationals
We settle Hindmanâ€™s conjecture over the rationals, proving that for every
coloring of the set of positive rationals by a finite number of colors and
for every integer n>1, there are n numbers x_1,..,x_n so that all of them,
all their subset sums and all their subset products have the same
color.
