I just wanted to know, isIs there any result knowknown about the following generalization of the Erdős-Ko-Rado theorem?
Let $n, k, r, s$ be positive integers. We call a family $\mathcal{F}$ of k$k$-subsetselement subsets of the set $\{1,\ldots, n\}$, an $(r, s)$-intersection family$(r, s)$-intersection family if among every $r$ elements of $\mathcal{F}$ at least two of them hashave an $s$- elements in theirelement intersection. What is the maximum size of such a family?
