RT journal article T1 On Ideals of Submonoids of Power Monoids A1 García García, Juan Ignacio A1 Marín Aragón, Daniel A1 Vigneron Tenorio, Alberto A2 Matemáticas K1 atomic monoid K1 elasticity K1 h-fold sumset K1 monoid ideal K1 non-cancellative monoid K1 power monoid K1 semigroup ideal K1 sumset AB Let (Formula presented.) be a numerical monoid, while a (Formula presented.) -monoid S is a monoid generated by a finite number of finite non-empty subsets of (Formula presented.). That is, S is a non-cancellative commutative monoid obtained from the sumset of finite non-negative integer sets. This work provides an algorithm for computing the ideals associated with some (Formula presented.) -monoids. These are the key to studying some factorization properties of (Formula presented.) -monoids and some additive properties of sumsets. This approach links computational commutative algebra with additive number theory.
