Lifting iso-dual algebraic geometry codes
MarÃa Chara, Ricardo Podestá, Luciane Quoos +1
In this work we investigate the problem of producing iso-dual algebraic geometry (AG) codes over a finite field with elements. Given a finite separable extension…
Bounds for the relative class number problem for function fields
Santiago Arango-Piñeros, MarÃa Chara, Asimina S. Hamakiotes +2
We establish bounds on a finite separable extension of function fields in terms of the relative class number, thus reducing the problem of classifying extensions with a fixed relat…
Good iso-dual AG-codes from towers of function fields
MarÃa Chara, Ricardo Podestá, Luciane Quoos +1
We present a simple method to establish the existence of asymptotically good sequences of iso-dual AG-codes. A key advantage of our approach, beyond its simplicity, is its flexibil…
A family of asymptotically bad wild towers of function fields
Maria Chara, Ricardo Toledano
In a previous work general conditions were given to prove the infiniteness of the genus of certain towers of function fields over a perfect field. It was shown that many examples w…
