Forbidden sparse intersections
Let n be a positive integer, let $0<p\leqslant p'\leqslant \frac 12$ , and let $\ell \leqslant pn$ be a nonnegative integer. We prove that if $\mathcal {F},\mathcal {G}\subseteq \{0,1\}^n$ are two families whose cross intersections forbid $\ell $ —that is, they sati...
