In the first part of this paper, we prove a theorem which is the $q$ -analogue of a generalized modular Ray-Chaudhuri-Wilson Theorem shown in [Alon, Babai, Suzuki, J. Combin. Theory…

Fractional cross intersecting families

Rogers Mathew, Ritabrata Ray, Shashank Srivastava

Let $A = {A_{1}, ..., A_{p}}$ and $B = {B_{1}, ..., B_{q}}$ be two families of subsets of $[n]$ such that for every $i \in [p]$ and $j \in [q]$ , $|A_{i}\cap B_{j}|= \…
