Squares and difference sets in finite fields

Christine Bachoc, Imre Z. Ruzsa, Mate Matolcsi

For infinitely many primes we give a slightly improved upper bound for the maximal cardinality of a set $B\subset \ZZ_p$ such that the difference set contains only q…

Spectral bounds for the independence ratio and the chromatic number of an operator

Christine Bachoc, Evan DeCorte, Fernando Mario de Oliveira Filho +1

We define the independence ratio and the chromatic number for bounded, self-adjoint operators on an L^2-space by extending the definitions for the adjacency matrix of finite graphs…
