<div align="left"><b><b><font color="#ff0000">Abstract:</font></b></b><font
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>
