Duals of multiplicity codes Camps Moreno, Eduardo Fidalgo Díaz, Adrián López Valdez, Hiram H. Martínez Peñas, Umberto Ruano Benito, Diego San José Rubio, Rodrigo Teoría de la información Matemáticas aplicadas Codificación de datos Producción Científica Multivariate multiplicity codes have been recently explored because of their importance for list decoding and local decoding. Given a multivariate multiplicity code, in this paper, we compute its dimension using Gröbner basis tools, its dual in terms of indicator functions, and explicitly describe a parity-check matrix. In contrast with Reed–Muller, Reed–Solomon, univariate multiplicity, and other evaluation codes, the dual of a multivariate multiplicity code is not equivalent or isometric to a multiplicity code (i.e., this code family is not closed under duality). We use our explicit description to provide a lower bound on the minimum distance for the dual of a multiplicity code. 2026-04-08T07:33:56Z 2026-04-08T07:33:56Z 2026 info:eu-repo/semantics/article Designs, Codes and Cryptography, 2026, vol. 94, n. 4, artículo 81. 0925-1022 https://uvadoc.uva.es/handle/10324/83961 10.1007/s10623-026-01812-2 4 Designs, Codes and Cryptography 94 1573-7586 eng https://link.springer.com/article/10.1007/s10623-026-01812-2 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2026 The Author(s) Atribución 4.0 Internacional Springer Nature SI
