Special divisors of large dimension on curves with many points over finite fieldsJosé Felipe Voloch (1) University of Texas at Austin, USA
We prove a non-existence result for special divisors of large dimension on curves over finite fields with many points. We also give a family of examples where such divisors exist under less stringent hypotheses.
Keywords: Algebraic curves over finite fields, special divisors, modular forms
