Finite group actions on Riemann Roch spaces and automorphisms
of algebraic geometry codes -- Amy Ksir

<p>


 I will review how the Riemann-Roch space of an algebraic curve
can be used to construct an error correcting code, and discuss
the relationship between automorphisms of the curve and of the
code. I will show that in many cases, the automorphism group of
a curve and the permutation automorphism group of a
corresponding AG code are the same.  Based on joint work with
