We point some contributions to the construction of Locally Recoverable codes from algebraic curves recently presented by A. Barg, I. Tamo and S. Vladut, that can lead to improvements concerning the definition, the parameters and the local recovering of these codes. I. INTRODUCTION Locally Recoverable (or LRC) codes were introduced in  motivated by the… (More)
We study Algebraic Geometry codes producing quantum error-correcting codes by the CSS construction. We pay particular attention to the family of Castle codes. We show that many of the examples known in the literature in fact belong to this family of codes. We systematize these constructions by showing the common theory that underlies all of them.
