Let F/IFq be a function field over a finite field ifq. We have seen in Chapter 5 that the number N of rational places of F over ifq satisfies the Hasse Weil Bound Nq + 1 + 2gq1/2, and that this upper bound can be attained only if g ≤ (qq1/2)/2. Here our aim is to investigate what happens if the genus is large with respect to q. The results of this chapter have interesting applications in coding theory, see Section 8.4.
