Abstract

Let KK be a global function field. We obtain a set of formulas for the densities of the Kodaira types and Tamagawa numbers of elliptic curves over a completion of KK that is independent of the field's characteristic. Furthermore, for a finite field FF and real numbers ss and ϵ\epsilon such that s>1s>1 and ϵ>0\epsilon>0, we prove that there exists a global function field KK such that the full constant field of KK is FF and the value of the zeta function of KK at ss is less than 1+ϵ1+\epsilon.
