On the regularity index of the minimum distance function in projective nested Cartesian codes

Cicero Carvalho, Maria Vaz Pinto, Rafael H. Villarreal

Let $X$ be a projective nested product of fields and let ${\delta }_X(d)$ be the minimum distance in degree $d\ge 1$ of the projective nested Cartesian code $C_X(d)$. The regularity index…
