A recursive construction for projective Reed-Muller codes

R San-José - IEEE Transactions on Information Theory, 2024 - ieeexplore.ieee.org
We give a recursive construction for projective Reed-Muller codes in terms of affine Reed-
Muller codes and projective Reed-Muller codes in fewer variables. From this construction …

On the minimum distance, minimum weight codewords, and the dimension of projective Reed-Muller codes

SR Ghorpade, R Ludhani - arXiv preprint arXiv:2309.10196, 2023 - arxiv.org
We give an alternative proof of the formula for the minimum distance of a projective Reed-
Muller code of an arbitrary order. It leads to a complete characterization of the minimum …

Hulls of Projective Reed–Muller Codes over the Projective Plane

D Ruano, R San-José - SIAM Journal on Applied Algebra and Geometry, 2024 - SIAM
By solving a problem regarding polynomials in a quotient ring, we obtain the relative hull
and the Hermitian hull of projective Reed–Muller codes over the projective plane. The …

[PDF][PDF] A note on Nullstellensatz over finite fields

SR Ghorpade - Contemporary Mathematics, 2019 - math.iitb.ac.in
We give an expository account of Nullstellensatz-like results when the base field is finite. In
particular, we discuss the vanishing ideal of the affine space and of the projective space …

Algebraic geometric codes on minimal Hirzebruch surfaces

J Nardi - Journal of Algebra, 2019 - Elsevier
We define a linear code C η (δ T, δ X) by evaluating polynomials of bidegree (δ T, δ X) in the
Cox ring on F q-rational points of a minimal Hirzebruch surface over the finite field F q. We …

Computing vanishing ideals for Toric codes

M Şahin - arXiv preprint arXiv:2207.01061, 2022 - arxiv.org
Motivated by applications to the theory of error-correcting codes, we give an algorithmic
method for computing a generating set for the ideal generated by $\beta $-graded …

Projective toric codes

J Nardi - International Journal of Number Theory, 2022 - World Scientific
Any integral convex polytope P in ℝ N provides an N-dimensional toric variety XP and an
ample divisor DP on this variety. This paper gives an explicit construction of the algebraic …

Recursive decoding of projective Reed-Muller codes

R San-José - arXiv preprint arXiv:2501.01692, 2025 - arxiv.org
We give a recursive decoding algorithm for projective Reed-Muller codes making use of a
decoder for affine Reed-Muller codes. We determine the number of errors that can be …

V Astore, M Borello, M Calderini, F Salizzoni - arXiv preprint arXiv …, 2024 - arxiv.org
Rank-metric codes have been a central topic in coding theory due to their theoretical and
practical significance, with applications in network coding, distributed storage, crisscross …

A combinatorial approach to the number of solutions of systems of homogeneous polynomial equations over finite fields

P Beelen, M Datta, SR Ghorpade - Moscow Mathematical Journal, 2022 - orbit.dtu.dk
We give a complete conjectural formula for the number er (d, m) of maximum possible F q-
rational points on a projective algebraic variety defined by r linearly independent …
