Weierstrass Pairs and Minimum Distance of Goppa Codes
We prove that elements of the Weierstrass gap set of a pair of points may be used to define a geometric Goppa code which has minimum distance greater than the usual lower bound. We...

On Goppa Codes and Weierstrass Gaps at Several Points
We generalize results of Homma and Kim [2001, J. Pure Appl. Algebra 162, 273?290] concerning an improvement on the Goppa bound on the minimum distance of certain Goppa codes.

On some invariants in numerical semigroups and estimations of the order bound
Let S = {si}iIN IN be a numerical semigroup. For si S, let (si) denote the number of pairs (si -sj, sj) S2 . When S is the Weierstrass semigroup of a family {Ci}iIN of one-point...

On the parameters of r-dimensional toric codes
From a rational convex polytope of dimension r ≥ 2 J.P. Hansen constructed an error correcting code of length n = (q−1)r over the finite field Fq. A rational convex polytope...

Locating sensors in paths and cycles: The case of 2-identifying codes
For a graph G and a set D V (G), define Nr[x] = {xi V (G) : d(x, xi) r} (where d(x, y) is graph theoretic distance) and Dr(x) = Nr[x] D. D is known as an r-identifying code if...
