Divisor's z
WebUsing the valuations, we can associate a divisor to any rational function f. De nition 2.6. Let f 2 (X) be a rational function on X. We de ne the divisor of fto be divf= (f) = X Z v Z(f)Z where the sum is taken over all prime divisors ZˆX. Remark 2.7. This sum is nite { that is, v Z(f) = 0 for all but nitely many prime divisors Z. http://drorbn.net/images/8/8a/08-401-HW1S.pdf
