            color="#ff0000"><font color="#000000"> Historically,
              questions about rational points on curves over finite
              fields occupy a prominent place in number theory. The
              introduction of the zeta functions for these curves by
              Artin led to an increased interest in this field, which
              culminated in the proof of the corresponding Riemann
              hypothesis by Hasse and Weil in the first half of the 20th
              century. After a long period, interest in this field was
              again reawakened in the 80's, when Goppa showed how this
              machinery from algebraic geometry can be used in the
              constructions of long codes allowing reliable
              communication over channels in the presence of errors.
              Using algebraic curves it became possible to beat the best
              constructions known to coding theorists and in the
              following decades many other applications in coding theory
              and cryptography followed. In this talk I will talk about
              recent results on the number of rational points on curves
              of large genus and their applications in the theory of
              error correcting codes.<br>
