Title:Curves over finite fields and error correcting codes

**
**Abstract:**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.
