Abstract:
We obtain a new bound on certain double sums of multiplicative characters which improves several previous results. This improvement comes from new bounds on the number of collinear triples in finite fields, which is a classical object of study in additive combinatorics.
Keywords:
finite field, character sums, collinear triples, multiplicative energy.
