Title: Some applications of linear algebra to extremal set theory

Abstract:

We begin with an inequality on the rank of a matrix with few distinct off-diagonal entries and relate this to families of multisets with few pairwise intersection sizes. It is useful to considerthe matrices modula primes $p$.
