A proof of the conjecture of Cohen and Mullen on sums of primitive roots

Cohen, Stephen D; Oliveira E Silva, Tomás; Trudgian, Tim


We prove that for all q > 61, every non-zero element in the finite field Fq can be written as a linear combination of two primitive roots of Fq. This resolves a conjecture posed by Cohen and Mullen.
