WebThe celebrated Frankl–Ray-Chaudhuri–Wilson theorems give tight bounds on the size of an L-intersecting set system on a ground set of size n. Such a system contains at most n s sets if it is uniform and at most s i=0 n i sets if it is nonuniform. They also prove modular versions of these results.

In case L 6= f0g, the Nonuniform Fischer Inequality improves the upper bound n+1 to n. A similar phenomenon occurs here as well: Theorem 1.3 is only sharp if all k-wise intersections are empty. fnb hazyview contact details
