A semigroup defining the Gröbner degeneration of a toric ideal
Hernán de Alba Casillas, Daniel Duarte, Raúl Vargas Antuna
We give an explicit set of generators for the semigroup of the Gröbner degeneration of a toric ideal. This set of generators is used to study algebraic properties of the semigroup…
