Connected domination in graphs and v-numbers of binomial edge ideals

D Jaramillo-Velez, L Seccia - Collectanea Mathematica, 2024 - Springer
The v-number of a graded ideal is an algebraic invariant introduced by Cooper et al., and
originally motivated by problems in algebraic coding theory. In this paper we study the case …

Frobenius methods in combinatorics

A De Stefani, J Montaño… - Sao Paulo Journal of …, 2023 - Springer
We survey results produced from the interaction between methods in prime characteristic
and combinatorial commutative algebra. We showcase results for edge ideals, toric …

On the -number of Gorenstein Ideals and Frobenius Powers

K Saha, N Kotal - Bulletin of the Malaysian Mathematical Sciences …, 2024 - Springer
In this paper, we show the equality of the (local)\(\textrm {v}\)-number and Castelnuovo-
Mumford regularity of certain classes of Gorenstein algebras, including the class of …

Relative generalized Hamming weights of evaluation codes

D Jaramillo-Velez, HH López, Y Pitones - São Paulo Journal of …, 2023 - Springer
This work aims to algebraically describe the relative generalized Hamming weights of
evaluation codes. We give a lower bound for these weights in terms of a footprint bound, and …

Regularity index of the generalized minimum distance function

C Espinosa-Valdéz, L Núñez-Betancourt… - Journal of Pure and …, 2024 - Elsevier
We show that the generalized minimum distance function is non-increasing as the degree
varies for reduced standard graded algebras over a field. This allows us to define its …
