We establish improved sum-product bounds in finite fields using incidence theorems based on bounds for classical Kloosterman and related sums.

We study the existence of non-special divisors of degree g and g − 1 for algebraic function fields of genus g ≥ 1 defined over a finite field Fq. In particular, we prove that there always exists an effective non-special divisor of degree g ≥ 2 if q ≥ 3 and that there always exists a non-special divisor of degree g − 1 ≥ 1 if q ≥ 4. We use our results to improve upper and upper asymptotic bounds...
