Modular representations on some Riemann-Roch spaces of modular curves X(N)

David Joyner, Amy Ksir

We compute the PSL(2,N)-module structure of the Riemann-Roch space L(D), where D is an invariant non-special divisor on the modular curve X(N), with N > 5 prime. This depends on a…

Automorphism groups of some AG codes

David Joyner, Amy Ksir

We show that in many cases, the automorphism group of a curve and the permutation automorphism group of a corresponding AG code are the same. This generalizes a result of Wesemeyer…
