Suzuki-invariant codes from the Suzuki curve

Abdulla Eid, Hilaf Hasson, Amy Ksir +1

In this paper we consider the Suzuki curve $y^{q} + y = x^{q_{0}} (x^{q} + x)$ over the field with $q = 2^{2 m + 1}$ elements. The automorphism group of this curve is known to be the Suzuki…

Automorphism Groups on Tropical Curves: Some Cohomology Calculations

David Joyner, Amy Ksir, Caroline Grant Melles

Let $X$ be an abstract tropical curve and let $G$ be a finite subgroup of the automorphism group of $X$ . Let $D$ be a divisor on $X$ whose equivalence class is $G$ -invariant. We ad…

Automorphism groups of generalized Reed-Solomon codes

David Joyner, Amy Ksir, Will Traves

We look at AG codes associated to the projective line, re-examining the problem of determining their automorphism groups (originally investigated by Duer in 1987 using combinatoria…

Group representations on Riemann-Roch spaces of some Hurwitz curves

David Joyner, Amy Ksir, Roger Vogeler

Let q>1 denote an integer relatively prime to 2,3,7 and for which G=PSL(2,q) is a Hurwitz group for a smooth projective curve X defined over C. We compute the G-module structure of…

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…
